Safety and First Aid

Personnel engaged in the installation, operation, maintenance, or servicing of electronic equipment

are exposed to the hazard of high voltage. It is imperative that all safety regulations and

precautions are consistently observed. Knowledge of first aid procedures is recommended. The

following information is presented as a reference only.

• At all times, avoid placing any part of the body in series between ground and circuit points,

whether power is on or off.

• Dangerous voltage may be present in equipment even though power is off. Do not open the

cabinet. Refer servicing to qualified service personnel.

• It is the duty of all personnel to be prepared to give adequate emergency first aid treatment and

thereby prevent avoidable loss of life.

• There are three principle degrees of burns, recognizable as follows:

• a first-degree burn reddens the skin.

• a second-degree burn blisters the skin.

• a third degree burn chars the flesh and frequently places the victim in a state of shock

accompanied by respiratory paralysis.

• Respiratory paralysis can cause death by suffocation within seconds. It is imperative that the

approved methods of artificial respiration are initiated immediately and continue until the victim’s

breathing is normal.

• A muscular spasm of unconsciousness may render the victim unable to break free of the

electric power. If this is the case, turn the power off immediately.

DO NOT TOUCH THE VICTIM OR YOU MAY SHARE THE SAME

PREDICAMENT.

• If the power cannot be turned off immediately, very carefully loop a dry rope, article of clothing,

length of strong cloth or a rolled-up newspaper around the victim and pull the victim free of the

power source. Carefully avoid touching the victim or clothing.

• Once free of the power source, the victim must be placed in a reclining position and covered

with a blanket or newspapers to keep warm. At the first opportunity, enlist help in

summoning a doctor. If a doctor cannot be summoned, transport the victim to the doctor or

a hospital. Be sure the victim is kept well covered and warm while awaiting professional

treatment.

Operating Safeguards

It is a known fact that our broadcast transmitters and translators enjoy 50-ohm load

impedances. So much so, that it is imperative you maintain 50-ohm impedances throughout

your system. In return, your equipment will provide you with maximum power transfer to the

antenna and decreased reflected power heading back towards the amplifier pallets, reducing

the amount of magic smoke that gets let out of the power amplifier. Before anything is turned

on, ensure that there is a 50-ohm path from the output of each stage to the input of the next, all

the way to the antenna.

In addition to maintaining proper 50-ohm impedances throughout the signal chain, it is also

important, whenever possible, to make sure the RF drive going to the input of the power

amplifier is removed before turning on or turning off the DC power supply. This is because all of

the RF transistors used in the individual amplifier pallets are fabricated with LDMOS (Laterally

Diffused Metal Oxide Semiconductor) technology. Nice and linear yes, but they do not like to

make any RF power when their supply voltages are not within a specific range. When you first

turn your power amplifier on or off, the DC power supply’s output voltage may take a while to

stable out to a safe operating voltage. Ten seconds wait before applying the RF drive will

ensure no issues arise.

Our power amplifiers are designed to reliably generate a specific RF output power. Failing to

adhere to overdriven amplifier warnings can decrease the reliability of your system, and frankly,

makes our repair department busy and grumpy. If you need to transmit to a little larger

coverage, you are better off increasing antenna gain, and more importantly, antenna height

above average terrain. On TV and FM broadcast frequencies, insufficient antenna height puts

an upper limit on your range, regardless of power levels, as the distance from your antenna to

the radio horizon is limited.

Principle of Operation

The TAUD-1000 power amplifier supplies a 1000-watt (rms) 8VSB television signal on any of the

UHF television channels 14 through 69. Please note that channel selection must be made at time

of order, as the transmitter or translator is calibrated and tested to the channel requested and is not

field tuneable. The TAUD-1000 power amplifier is a modular solid-state 1000-watt broadcast

amplifier utilizing readily available RF components wherever possible, thus enhancing the

serviceability of the equipment.

The TAUD-1000 is comprised of two TAUD-500 500-watt RMS power amplifiers that get combined

to create the 1,000-watts RMS 8VSB RF signal, as illustrated in the following block diagram

Inside each of the 500-watt RMS power amplifiers, the signal passes through an RF attenuator

to limit the output power level of the power amplifier and to help buffer any transients that may

come into the power amplifier. After attenuation, the signal gets preamplified through a UHFTV-

50 driver amplifier before the signal gets split into (3) signals for final amplification using a 3-way

microstrip power divider. The final amplification stage is comprised of (3) BLF878 final

amplifiers. The outputs of the (3) final amplifier pallets are combined with a 3-way microstrip

combiner and pass through an isolator as illustrated in the following TAUD-500 block diagram.

After the isolator, the signal passes through a dual directional coupler before heading into the

combiner/filter enclosure.

After amplification, the signal exits the power amplifier enclosure and goes into the filter/coupler

enclosure. The two RF signals from each of the TAUD-500 amplifiers (500-watts RMS) get

combined by a 2-way, 90 degree combiner via phased cables. The amplified signals are filtered

with a bandpass filter and monitored again with another directional coupler before heading out

to the customers inline 8VSB reading wattmeter and then to an antenna for broadcast, as

Section IV – RF Components

Amplifier Pallets

The UHFTV-50 driver pallet is also a linear class-AB pallet. It has a typical gain of 37dB and draws

no more than 3.0Adc total drain current. The quiescent and drain currents can be measured on the

UHFTV-50 by inserting an ammeter in series with the power supply lead to the pallet or by

measuring the voltage drop across the current sense resistor found directly at the DC power supply

lead input to the pallet. This resistance is 0.01-ohms, providing a 10mV per ampere ratio.

The BLF878 pallets used in the final amplification stage use LDMOS (Laterally Diffused Metal Oxide

Semiconductor) technology. LDMOS technology offers higher gain, efficiency and linearity over

standard MOSFET and Bipolar devices and enhances ruggedness and reliability. LDMOS

transistors have the added advantage of not having BEO (Beryllium Oxide) in their construction.

The BLF878 amplifier pallets have a typical gain of 17dB and draw no more than 25Adc. Currents

for these pallets must be measured with an ammeter in series with the power supply lead.

Each of the amplifier pallets is connectorized to optimize servicing and accessibility

Technalogix Ltd TAUD-1000 Transmitter

IV-4

Power Divider/Combiner (internal to each TAUD-500 enclosure)

A Wilkinson power divider and combiner (identical printed circuit boards) are used to split the RF

signal into, and combine the amplified RF signal out of the (3) BLF final amplifier pallets. Flanged

power resistors help ensure that any differences between the inputs or outputs are balanced.

The Wilkinson design takes advantage of the fact that an impedance transformation can take place

across a quarter-wavelength transmission line if the line has different impedance than the source or

load impedances being matched. In this case, quarter-wavelengths of 75-ohm coaxial are used to

maintain 50-ohm impedances at the input and output of the Wilkinson divider/combiner. Due to its

electrical and mechanical symmetry, the Wilkinson design’s performance over moderate

bandwidths is superior to other types. This design maintains phase and amplitude equality, in

addition to providing isolation and matched outputs.

Splitter/Combiner

The splitter and combiner are used to split the RF signal into, and combine the amplified RF signal

out of the (2) final amplifier pallets. The connectorized designs are based on the simple isolated

Wilkinson combiner design. Due to its electrical and mechanical symmetry, the Wilkinson design’s

performance over moderate bandwidths is superior to other types.

Directional Coupler

The Technalogix dual directional coupler provide DC voltages proportional to forward and reflected

RF power monitoring. These analog voltages are converted for processing using analog-to-digital

converters and provide the control system with valuable data for monitoring purposes. Output power

should be set following the operating procedure found elsewhere in this manual. The directional

coupler has a typical insertion loss of 0.5dB and its Type N connectors can handle 1,500 watts

peak. On higher power systems, 7/16 DIN connectors are used for increased power handling

capability.

Isolator

The power amplifier pallets are protected in part by the isolator located in the filter enclosure. It is

actually made up of a circulator and 50-ohm dump resistor. The circulators’ specifications include

an insertion loss of less than 0.2dB with an isolation rating better than 20dB. Any reflected power

gets dumped into the flanged power resistor. Even though the flanged power resistor is rated for

less than the transmitter’s rated power, the software will recognize quickly that reflected power is

present and turn the carrier off. This way, there is instantaneous protection due to the isolator setup

and long term protection due to the software.

Technalogix Ltd TAUD-1000 Transmitter

IV-5

Filter

The passive bandpass filter rejects spurious and harmonic output products and passes the channel

RF output. The cavity resonator uses aperture coupling and is a linear resonator design. Typical

insertion loss is 0.4 dB to 0.6 dB depending on channel frequency. The filter is DC grounded on

both the input and output for additional lightning protection.

Technalogix Ltd TAUD-1000 Transmitter

V-1

Section V – Power Supply

Switching AC-DC power supplies are used to power the amplifier pallets, the control circuits, and all

of the fans. There are switching supplies in the Power Supply enclosure that feed all of the amplifier

pallets and fans inside each of the two TAUD-500 amplifier enclosures that make the 1,000-watts

RMS. In addition, the Combiner/Filter enclosure has a small switching supply to feed the control

circuitry in that enclosure.

The power supplies found in the Power Supply enclosure are (2) Meanwell RSP-3000-48. The

switching power supply is fully protected against short circuit and output overload. Short circuit

protection is a cycling type power limit. The internal AC fuse is designed to blow only on a

catastrophic failure in the unit – the fuse does not blow on overload or short circuit. The thermal

shutdown automatically recovers when the power supply chassis cools down. AC (220Vac) is fed

into the power supply enclosure via a resettable circuit breaker. The power supplies are set at

48.0Vdc nominally. All fans in the Power Amplifier enclosure run off this same supply.

The power supply found in the Combiner/Filter enclosure is a Meanwell S60-24. It powers the

control PCBS in the Combiner/Filter enclosure. Its output voltage is set to 24.0 Vac.

Section VI – Monitor and Control System

Control System Overview (Adrenaline)

The Adrenaline control system is used for a variety of functions, the most important of which is

ensuring that the transmitter continues to operate in a safe manner. The control system also

allows the user to monitor and control the transmitter from both the front panel and remotely

through the parallel port, Ethernet, or SNMP access port (some features optional).

The Adrenaline control system is comprised of three modules. These modules work together to

provide all the functions of the control system and include: Display Interface, RF, and

Temperature Sensor modules. In higher power/multiple pallet systems, a fourth module (DC

Distribution) is included. The operation of each module is outlined in the following sections and

illustrated in the following block diagram.

Display Interface Module

REV 1.01 (ASY 015)

Touchscreen Option

The primary function of the Display Interface module is, as the name suggests, providing the

display and user interface for the control system. This circuit board is mounted behind the front

panel of the power amplifier enclosure(s) in the transmitter/translator, near the 4.3” touchscreen

display. All switch/settings and user interface is handled through the resistive touchscreen. The

touchscreen on the front panel is connected to the Display Interface PCB through a cable.

These components provide the user with the ability to monitor the following power amplifier

parameters from the front panel:

• Forward (incident) power at the power amplifier output.

• Reflected (reverse) power at the power amplifier output.

• DC voltage of the power amplifier’s power supply.

• DC current in the power amplifier.

• Temperature of the heat sink of the power amplifier.

• The time since the transmitter/translator was last shut down.

• Full history of faults and events

• Mode of the power amplifier (selectable between Manual and AGC).

• Indication if there is attenuation added to the front end of the power amplifier indicating

fold back in RF power (indicates amount of attenuation)

• Settings to change the VSWR trip point shutdown between 1.1:1 and 1.8:1.

• Settings to change the RF power units between % power (maximum of 110%) or watts.

• Summary of PCB modules and assembly numbers specific to the power amplifier

A block diagram of the Display Interface PCB follows:

Technalogix Ltd Adrenaline Control System

VI-4

The hardware of the Display Interface module is based around microcontroller (U101). This part

interfaces directly with the touchscreen to provide output and receive input from the user. It

also communicates with the RF board (and DC Distribution Module, if installed) over a

Controller Area Network (CAN) bus. This communication is facilitated by U103, and passes

through a CAT5 cable attached to connector J104. The communication link with the RF module

allows the Display Interface Module to receive information about the forward power, reflected

power, and temperature of the transmitter, as well as relay commands from the user to the rest

of the system. If the DC Distribution Module is installed (on higher power systems with multiple

pallets), then the Display Interface receives DC currents from the DC Distribution via the same

CAN bus.

Other elements of the Display Interface module are also controlled by the microcontroller. A

buzzer (BZ101) and software status LED (D101), which flashes when the software /

microcontroller is running, are all controlled through a buffer (U102). DC supply enters through

connector J103, which powers the PCB and also the optional DC-DC converter (based around

U111), if populated. The PCB voltage is regulated at +5V by U106 and associated circuitry. If

the PCB is populated for FM broadcast, then the PWM filter circuit (based around U104) is also

populated and provides a DC output control voltage on pin 3. The touchscreen interfaces to the

Display Interface via connector J107.

The fuses on the Display Interface are all resettable. F102 protects the +5V line while F101

protects the DC-DC converter, if installed.

Main Screen

From the screen shot of the main screen, as seen in the figure below, all of the system’s main

parameters can be viewed at a quick glance. The three main sections of this screen are the four

level bars, the summary bar at the bottom of the screen, and the carrier ON/OFF button. The

level bars show real time system performance and help illustrate any transient changes that

occur. The FORWARD POWER and REFLECTED POWER level bars can also be shown in

watts (a full description of how to do this is found in the SETTINGS section. The summary bar at

the bottom of the screen will stay in place no matter what screen is being viewed to allow for an

operating summary at any time. Also from any screen, the transmitter’s carrier can be turned on

or off to facilitate adjustments, settings, and testing/troubleshooting.

The following breakdown describes the Main Screen features in further detail:

Toggles between Main Screen and Menu Screen. The menu screen has

additional settings and monitoring over the Main Screen, and is illustrated in the

next section.

Forward RF power level in % out of 100 or watts. Mimics data from level bar.

Overdrive protection starts at 110% where the power amplifier folds back power

by adding attenuation to the power amplifier input until a safe level obtained.

System continually checks power level and tries to bring RF power level back to

where it was when the fault occurred. If overdrive occurs, a warning is also

displayed in red text near the top of the touchscreen and the event recorder logs

the event.

Technalogix Ltd Adrenaline Control System

VI-11

Reflected RF power level in % out of 100 or watts. Mimics data from level bar.

The high VSWR fault occurs when the measured VSWR of the system exceeds

the user-defined VSWR trip point found in the RF Power Menu, described later in

this section. If the VSWR exceeds the user defined shutdown level, but is below

1.8:1, then attenuation is added to the power amplifier input until a safe level is

reached. If the measured VSWR exceeds 1.8:1, then the RF carrier is turned off

to protect the amplifier chain. At this point, the system will continually check to

see if it is safe to come back on. This protection scheme helps ensure that the

system stays on the air as long as possible before doing a complete shutdown. If

high reflected power occurs, a warning is also displayed in red text near the top

of the touchscreen and the event recorder logs the event.

Temperature from sensor mounted on heat sink surface. Shutdown trip point is

factory set at a predetermined level to keep the amplifier pallets safe. Should a

fan fail inside the power amplifier enclosure, or air conditioning fails inside the

broadcast facility causing the temperature to exceed the trip point, the control

system will lower forward RF power until a safe level of measured temperature is

achieved. The system will continually try and bring the RF power back to the

same level when the fault occurred if it is safe to do so, a warning is displayed in

red text near the top of the touchscreen, and the event recorder logs the event.

RF output power is determined largely in part by the amount of attenuation that

the control system places on the input of the power amplifier. Whether a fault

occurs and attenuation gets added or the user requests a change in RF power

level via the web/SNMP/Remote Port interface, the attenuation section of the

summary bar conveys important operating information. If the user requests a

change in forward power level via the web interface, SNMP monitoring and

control, or simply via the Remote Port connector on the back of the enclosure,

and an asterisk (*) is placed next to the attenuation value in the summary bar.

This informs the user whether or not the attenuation was added due to a fault or

simply because it was requested.

Automatic Gain Control or Manual mode. In AGC mode, the control system

maintains a user-settable forward RF power level by monitoring output power

and making slight adjustments as necessary. In Manual mode, the forward RF

power level is adjusted from the touchscreen via the RF Power Screen described

later in this section. If a fault occurs while the system is in AGC mode, the system

kicks out of AGC mode, goes into Manual mode, and the fault procedures are

followed. The user can toggle back and forth from AGC and Manual modes by

going to the RF Power Screen and changing the mode.

Technalogix Ltd Adrenaline Control System

VI-12

Date and Time. Displays current date and time. Power amplifiers ship from

factory with default Mountain Standard Time (MST). Users can adjust this info

from the Date and Time Screen. The event recorder pulls this info when it logs an

event so the user can correlate events in the field. Events stored prior to a date

and/or time change will maintain their original event stamp and will not be

modified to reflect the change. A Real Time Clock holds time for about one week

without AC power.

Carrier ON/OFF switch. By pressing the toggle switch on the touchscreen, the

user can turn on or off the RF carrier. The same result occurs by turning on or off

the system via the web or SNMP interface, or through controlling of the Remote

Port. A quick beep from the on-board buzzer signifies that the response has been

taken. The power supplies and fan will remain active while the carrier is turned

off via this switch.

Technalogix Ltd Adrenaline Control System

VI-13

Menu Screen

The menu screen allows the user to dive into further details of the power amplifier’s operations.

Pressing the BACK TO MAIN button will toggle between the Main Screen and the Menu Screen.

The Menu Screen is shown below:

Each of the menu icons on the Menu Screen allow the user to take additional readings or make

settings that are not provided from the Main Screen. Any changes to settings will be stored in

non-volatile memory with the exception of the date and time which are stored as long as the

backup battery remains charged (approximately one week of loss of AC power or power down).

While the user is in the sub menu screens (anything besides the Main Screen), full monitoring

and protection is taking place. This means that is a user makes a change to a setting or

parameter that jeopardizes the power amplifier, the control system will provide protection,

display the fault in red text near the top of the touchscreen, and stay in the current menu.

The individual menu screens will now be covered.

Technalogix Ltd Adrenaline Control System

VI-14

RF Levels Screen

This screen allows the user to change settings to the RF levels, including the Forward RF level

and the reflected (VSWR) trip point. From this screen, the user can also toggle between AGC

and Manual mode. The RF Levels Screen is displayed below:

To adjust Forward RF Level:

Press the up or down arrows until the desired Forward RF level is reached. If the adjusted level

exceeds 110%, the protection will kick in and the system will fold back the RF power to a safe

level. There may be a residual amount of Forward power even at 0% setting, but it should be

insignificant.

To toggle between Manual and AGC Mode:

Simply press the CHANGE TO MANUAL or CHANGE TO AGC button in the Adjust Levels half

of the screen. If a fault occurs while in AGC mode, the system will default back to Manual mode

and protective action will be taken.

NOTE: Pressing the up and down arrows for Forward RF level change while in AGC will

change the power. The same holds true for Ethernet, SNMP, or Remote Port control The AGC

is designed to hold the RF power level steady when the system is unmanned for external events

like temperature, slight changes to the input level, and long term component fatigue.

To change the VSWR Shutdown Trip Point:

Use the up and down arrows to set the VSWR shutdown trip point to between 1.1:1 and 1.8:1. If

a measured VSWR is found above the set trip point, but below 1.8:1, then the system will fold

back the forward power to a safe level. If the measured VSWR exceeds 1.8:1, then the carrier

will be initially turned right off.

Technalogix Ltd Adrenaline Control System

VI-15

Power Supplies Screen

This screen allows the user to view individual voltage and current readings. The Power Supplies

Screen is displayed below:

DC supply voltages are nominally 30 or 48Vdc depending on the system. Readings of this

voltage in the Power Supplies Screen, and on the summary bar at the bottom of the

touchscreen, should not vary more than +/- 2%.

If multiple amplifier pallets are included in the amplifier chain, then the individual currents will all

be displayed in the Currents section of the screen. In the case of multiple pallets in the chain,

typically the user should see matching of the final pallets to within approximately 10%. Anything

outside this range is usually a sign that there may be an issue. Transistor device or circulator /

isolator load damage could be the culprit, or the tragic spilt-drink-on-transmitter incident. Our

team would be glad to walk you through any troubleshooting issues or questions you may have.

Technalogix Ltd Adrenaline Control System

VI-16

Remote Interfacing Screen

The Remote Interfacing Screen is simply a summary of what features are installed into the

control system, as seen in the following screen shot.

The Remote Port, or parallel data, through the DB25 connector on the back panel of the

enclosure extracts the majority of the internal system information and provides it externally for

processing and control. The Remote Port is the equivalent of a standalone external remote

monitor.

The Ethernet web server provides a means to monitor system information via a web site. This is

accomplished via the Ethernet connector on the back panel of the power amplifier. The unit’s IP

address is listed in the Version Screen.

The SNMP offers a third method of monitoring system parameters and external control. The

user’s Network Management System (NMS) can monitor multiple transmitter sites remotely and

control common functions of the system via the Technalogix Management Information Base

(MIB).

Detailed information on all three remote interfacing subsystems is found later in this section.

Technalogix Ltd Adrenaline Control System

VI-17

History Screen

The History Screen provides a summary of the most recent events that have occurred in the

power amplifier, including the date and time of occurrence. An event can either be a fault or

simply an action like turning on or off the carrier. The format of the History Screen is illustrated

below:

Ten of the most recent events are displayed on the History Screen. As more events occur, the

earliest recorded event gets displaced on the screen. If the user changes the time and/or date

from the Date and Time Screen, then the events that occurred before the time and/or date

change remain unchanged with their original time stamp.

The user can clear the history screen by pressing the CLEAR HISTORY. Users will find this

screen useful in correlating events in the power amplifier with external events like weather and

changes to the broadcast facility’s environment.

The events are recorded in non-volatile memory so they are safe in the event of a power outage

Date and Time Screen

The Date and Time Screen is used to update the date and time of the control system. This is

typically used to create accurate correlations between the event history and events that are

external to the system.

The time is factory set to the factory’s Mountain Standard Time (MST).

Changes to the date or time are made by simply pressing the up or down arrows associated

with each section (month, day, hour, etc). Any changes will immediately be seen in the

summary bar on the bottom right of the touchscreen. When the changes are made, simply press

the BACK TO MAIN button to continue to other screens.

Version Screen

The Version Screen contains no user-settable items, but is intended as an identification screen

to the user. It also helps Technalogix maintain its unmatched service reputation by allowing our

technicians and Service team to know exactly what versions of PCBs are inside a customer’s

unit, even several years down the road. The versions can then be correlated to factory

documentation. In addition, current government certification numbers are included for Industry

Canada and FCC. Please contact Technalogix if you require copies of the actual grants, or visit:

FCC: https://fjallfoss.fcc.gov/oetcf/eas/reports/GenericSearch.cfm (grantee code QH5)

Ind. Canada: http://www.ic.gc.ca/app/sitt/reltel/srch/nwRdSrch.do?lang=eng (company 3803)

Finally, general information is included in the Version Screen for users who may not be familiar

with the equipment and do not want to venture into the dusty abyss behind the rack or cabinet

searching for tiny ID tags. The Version Screen is illustrated below:

Settings Screen

“You say tomato...”

The Settings Screen allows the user to modify some of their preferences on how information is

displayed on the touchscreen, as seen in the figure below:

Pressing the DEGREES F button will convert all temperature readings to degrees Fahrenheit

from Celsius (and vice versa). Temperature protection trip points are factory set.

Similarly, the user can switch between watts or percentage for their RF power readings. When

in percentage mode, the power amplifier is designed for a maximum operating power of 100%

with overdrive protection at 110%.

DC Distribution Module

REV 1.01 (ASY 085)

The DC Distribution module takes DC from the system’s power supply, splits it up for drivers,

finals, and fans, and monitors the current draw of the individual loads for protection, as seen in

the following block diagram:

DC is fed into the module via connectors J313 and J314 for the drivers and fans and J315

through J322 for the finals. The DC currents are then monitored for both display and protection

purposes. U308, U310, U312, U314, U316, U318, and U322 convert voltage drops across

current shunts for display purposes (sent to Display Interface), while U307, U309, U311, U313,

U315, and U317 handle high speed protection duties. The shutdown interface circuit takes

internal current faults and external inputs and processes them through an OR/NOR gate before

the shutdown signal heads off board. The DC current measurements that are to be used for

display purposes are also filtered via op amps U301 through U306, and U323. DC voltage is

monitored through U324.

Microcontroller U325 handles the interface between the Display Interface and the DC

Distribution and also converts the DC currents into a format suitable for sending through CAN to

the Display Interface. U321 handles the actual CAN bus data transfer.

The same DC that feeds the drivers and fans also powers the on board regulator (U326) that

generates the +5V. The green LED D302 provides visual indication that the 5V is present and

fuse F301 is good. Two yellow LEDs, D303 and D304, provide visual indication that the DC

supply inputs are present for both the drivers/fans and finals, respectively. A flashing D301

(orange LED) indicates that the software is running.

Temperature Sensor Module

REV 1.11 (ASY 181)

The Temperature Sensor module is a small board mounted to the main heatsink of the amplifier.

The main purpose of the temperature sensor module is to take temperature readings of the

heatsink. The following is a block diagram of the Temperature Sensor module:

The temperature sensor IC is U701 which, after it has taken a reading, relays the digital

information to the RF PCB module through J702. Also passing through J702 is a driver disable

signal coming from the RF PCB module. The Temperature Sensor module simply takes this

signal and passes it through to a pad, where a wire connects it to the driver or first gain stage

pallet.

RF Module

REV 1.01 (ASY 002)

The RF PCB module is located on the back panel of the power amplifier enclosure(s) and has

several primary functions:

• act as a variable attenuator so the control system can add attenuation to the RF input of

the power amplifier in order to limit the output power of the transmitter/translator,

• monitor the output of the directional coupler which provides a voltage proportional to the

forward and reflected power at the output of the transmitter/translator,

• communicate with the Temperature Sensor module to read heatsink temperatures and

provide a link to the driver shutdown through the temperature sensor PCB, and

• provide external remote operation to the user through parallel data, Ethernet, and SNMP

interfaces.

These functions can be seen by the block diagram:

The RF input signal comes in to the RF module through J214 (BNC female) or J217 (N female)

before it passes through a phase adjust circuit (installed only in multiple power amplifier

systems) made up of U227/U231 and associated circuitry. The signal then passes through the

voltage-controlled variable attenuator, U236. This attenuator is controlled via DAC (U209) and

buffer (U226) via the microcontroller. Finally, the low level RF signal exits through J207 (BNC

female).

The RF coupled signals produced by the coupler for forward and reflected power are passed

onto the RF module by connectors J203 and J220, respectively. Each signal is then converted

to a DC voltage proportional to the RF levels by detector ICs U229 and U241. The DC voltages

are buffered and filtered via CLC networks before being sent to the microcontroller (U219) and

comparator (U218) for monitoring.

Aside from taking readings from the coupler, the microcontroller on the RF module also

interfaces with the Temperature Sensor (through J211). The high speed shutdown signal for the

pallets is also passed through the Temperature Sensor PCB from the RF module. The lower

speed shutdown for the pallets or control is passed through pin 6 on J201. The microcontroller

interfaces with the system CAN bus using U234 transceiver. Through the CAN bus, the RF

board is able to communicate with the Display Interface module, and any other amplifier

enclosures that are in the system.

The last task of the RF board is to send and receive remote access signals to and from the

transmitter/translator. Two analog outputs, proportional to forward and reflected power and

produced by the digital potentiometer U222 after it receives input from the microcontroller. The

analog outputs are then buffered by U208 before being sent to the DB25 parallel output

connector, J215. J215 also carries the digital fault flags and input/output controls. The digital

signals are then connected to the microcontroller through the opto-isolators U211, U213, U214,

U215, and U237. The Remote Port allows external control of the transmission system via the

DB25. The Power Amplifier enclosure does not include all the pins in the Remote Port like the

Combiner/Filter enclosure.
