APPLICANT: MOTOROLA EQUIPMENT TYPE: ABZ89FC3797 EXHIBIT D1-4 User / Operational Manual Tune-Up Procedure (Draft) See the following manual excerpts (Chapter 10 and Chapter 13 of MOTOTRBO MTR3000 Base Station / Repeater, Basic Service Manual) for instruction on performing the field digital upgrade, operational verification, and programming / tuning. All adjustments are software controlled and are pre-set at the factory. Certain station operating parameters can be changed using Customer Programming Software (CPS), within predetermined limits. Examples include transmit / receiver operating frequencies and transmitter power level. After the base station / repeater and ancillary equipment have been mechanically installed, properly cabled, and power applied, the equipment must then be optimized; that is, before placing the base station / repeater in operation. The cable required is a standard “USB A to B” cable. Optimization is performed through the Customer Programming Software (CPS), kit number RVN5115. After the base station / repeater is operational, the base station / repeater’s codeplug data must be copied to a PC- compatible computer. Optimization involves the following tasks: 1. Reading the base station / repeater codeplug from the base station / repeater (this ensures a match between the base station / repeater serial number (resident in the codeplug) and the serial number (part of the customized base station / repeater codeplug data) that is written back to the base station / repeater (see task 5). 2. Customizing the base station / repeater codeplug and saving the data to the base station / repeater. 3. Aligning the base station / repeater for: - Modulation Limit - Speaker Level - Station Reference - MTR2000 PA Calibration - Receiver Squelch Adjust 4. Performing post-optimization procedures. 5. Writing the customized codeplug to the base station / repeater codeplug. For details on these tasks, refer to the Customer Programming Software (CPS) Online Help.

MTR3000 Programming and Tuning: Base Station/Repeater Tuning Setup 13-313.3 Base Station/Repeater Tuning SetupA personal computer (PC), Windows TM operating system, and the MOTOTRBO Tuner application are required to tune the Station. To perform the tuning procedures, the base station/repeater must be connected to the PC and test equipment setup as shown in Figure 13-4.Figure 13-4 MTR3000 Base Station/Repeater Tuning Equipment Setup13.4 Tuning Setup (MTR2000 MOTOTRBO Digital Upgrade)13.4.1 MTR2000 Calibration Coefficient EntryThis feature is used to allow entry of the transmitter (Tx) output power coefficients of an MTR2000 Power Amplifier (PA) into the MTR3000 tuning codeplug. Since an upgraded MTR2000 Base Station/Repeater does not have its PA upgraded, its PA calibration coefficients must be entered into the tuning codeplug, as the non-upgraded MTR2000 PA does not have an Electrically Erasable Programmable Read-only Memory (EEPROM). The calibration coefficients, which exist on a sticker on the face plate, consist of two 7 digit hexadecimal numbers and two 6 digit hexadecimal numbers. The sticker itself is created and applied at the factory in which the PA was calibrated.Note Section 13.4 on page 13-3 only applies to an upgraded MTR2000 Base Station/Repeater.

MTR3000 Programming and Tuning: Tuning Setup (Wireline) 13-513.4.1.2 Verification or Test Procedure for Low/High Power1. Power the Station from either an AC or DC source.2. Connect the radio’s Tx antenna port, through an attenuation pad and calibrate the path loss, to the Communication Analyzer.3. Via the CPS, program the radio with all user frequencies supported by the base station/repeater in analog mode.4. Enter the test frequency into the Communication Analyzer and set the analyzer in power meter mode.5. Connect a Mic to the RJ45 connector at the front panel.6. Press the PTT button on the Mic.7. Measure the transmit power.8. If the measured transmit power is not within the original MTR2000 specifications range, the PA must be replaced as it cannot be calibrated in the field.9. Repeat Step 4 to Step 7 for the remaining frequencies.13.5 Tuning Setup (Wireline)13.5.1 Wireline Receive Level TuningThe procedure outlined in this section is used to set the output level on the Wireline board’s Rx path for a given RF signal deviation on the received signal. Perform this procedure during initial Wireline installation or any time the Rx audio level needs adjustment.13.5.1.1 Tuning Procedure1. Connect the radio’s receiver antenna port to the Communication Analyzer.2. Power the base station/repeater from either an AC or DC source.3. Launch the Tuner application and click the “Read” button to read the softpot values.4. Select “Wireline Receive Level” under the Rx menu in the tree view (Refer to Figure 13-6).Figure 13-6 Rx Menu tree (Wireline Receive Level)APPLICANT: MOTOROLAEQUIPMENT TYPE: ABZ89FC3797EXHIBIT D1-4
13-6 MTR3000 Programming and Tuning: Tuning Setup (Wireline)5. Set the Communication Analyzer to output a -47 dBm RF signal modulated with a 1 kHz tone at 60% of full deviation on the tuning frequency. The tuning frequency is the value displayed on the Tuner GUI under the heading of “Frequency Points”.6. Adjust the softpot value until the desired receive audio level is achieved (-30 dBm to +7 dBm) across line two of the J6 Wireline backplane connector terminals.7. Click “Write” to save the new tuned softpot value into the radio’s codeplug.13.5.2 Wireline Rx Equalization – 2800 Hz TuningThe Rx Equalization feature allows the frequency response adjustment of the Rx Audio relative to a specified rated system deviation, to compensate (equalize) for the response of the wireline backhaul network itself. This section outlines the procedure for high frequency adjustment. Perform this procedure only after setting the Wireline Receive Level. Refer to Section 13.5.1 on page 13-5.The Rx Equalizer is adjusted relative to the response at 1 kHz. Note the 1 kHz response observed when performing the tuning procedure for Wireline Receive Level. Equalizer adjustments are approximate. Typical adjustments range from 0 dB to approximately +6 dB. Note The Tuner aligns this parameter in a 12.5 kHz channel spacing, so 60% is 1.5 kHz ofdeviation. If the CPS is set for 25 kHz operation, the base station/repeater will automaticallyscale the deviation by a factor of two when it is outside the Tuner environment.Note Programmed TPL and DPL squelch requirements are automatically disabled for the tuningfrequency while in the Tuner environment. Note It is imperative that the load the Wireline board is driving, matches that of the Wirelineboard’s source impedance setting noted in the Tuner environment.

APPLICANT: MOTOROLA EQUIPMENT TYPE: ABZ89FC3797 User / Operational Manual Functional Description / Operation of Modules (Draft) EXHIBIT D1-6 Base Radio Module Overview The Motorola MTR3000 Base Station / Repeater (BR) provides a modular, flexible analog and digital station design for today's communication systems and of the future. The stations are available for use in Analog Conventional, Digital Conventional (MOTOTRBO), LTR Trunking, Passport Trunking, MOTOTRBO Capacity Plus Trunking, and MOTOTRBO Connect Plus Trunking configurations. The MTR3000 BR can either be configured as a stand-alone base station / repeater or as a base station / repeater connected to a back-end network, as in the case of operating in IP Site Connect mode. As a base station / repeater, it listens on one uplink frequency, and then re-transmits on a downlink frequency thus providing the RF interface to the field subscribers. When configured for analog station operation, the BR is designed to operate with most existing analog systems, therefore making a smooth migration to the MOTOTRBO system. When configured for digital operation, the BR offers additional services. The digital BR operates in TDMA mode, which essentially divides one channel into two virtual channels using time slots; therefore the user capacity is doubled. The BR utilizes embedded signaling to inform the field radios of the busy/idle status of each channel (time slot), the type of traffic, and even the source and destination information. Note: When configured in Digital Mode, the BR can only be used as a repeater. Note: At any given time, the BR either operates as a digital repeater or as an analog repeater. The MTR3000 BR is divided into functional modules that separate the frequency band specific and transmitter power specific circuits from other circuits and has separate modules for the control interface. These modules are self contained functional blocks with module-specific alarms. This design facilitates the field replaceable unit (FRU) concept of field repair to maximize system uptime. Indicators and Connections This section describes the LED indicators and connectors provided on the base station / repeater. The set of LEDs indicate the operational status of the base station / repeater. There are two sets of connectors for devices external to the base station / repeater: • One set connects to external devices to enable full operation of the base station / repeater. These are located at the back of the base station / repeater. • Another set connects to external devices for servicing the base station / repeater. These are located on the Station Control Module. LED Indicators A set of eight LEDs is located on the base station / repeater front bezel. The position of the eight LEDs on the front bezel is shown below. These LEDs indicate the status of the base station / repeater during normal operation. Front Bezel LEDs and Connectors After booting up the base station / repeater, the six LEDs (Power/Status, TX Slot 1, TX Slot 2, RX Slot 1, RX Slot 2 and the Mode LEDs) flashes in unison. The general status and condition of the MTR3000 Base Station / Repeater can be obtained by observing the eight LED indicators on the front bezel.

Control Overview The Station Control Module (SCM) is described in this section. A general description, identification of controls, indicators, and inputs/outputs, a functional block diagram, and functional theory of operation are provided. The information provided is sufficient to give service personnel a functional understanding of the module, allowing maintenance and troubleshooting to the module level. General Description The SCM circuitry performs the digital signal processing, data formatting and audio routing for the base station / repeater (BR) and provides the external interfaces to the rest of the site. The SCM uses two TI OMAP1710 processors: - One for transmit and overall BR control functionalities - One for all receive functionalities Both OMAP1710 processors have independent boot Flash and RAM and, therefore can boot independently. General SCM functionality includes: • Data and Control interface to the Receiver’s Abacus III devices • Data and Control interface to the Exciter’s Trident chip set • Audio Codec interface with MAKO IC • Host memory size, speed, and types supported • External ports (Ethernet, USB, speaker and microphone) • External physical interfaces (switches, connectors, LEDs, external references etc.) • TX/RX DSP Multi-Channel Buffered Serial Port (MCBSP) interfaces • Intermodule communication (using SPI) • Internal station reference generation Functional Theory of Operation The following theory of operation describes the operation of the SCM at a functional level. The information is presented to give the service technician a basic understanding of the functions performed by the module in order to facilitate maintenance and troubleshooting to the module level. TX OMAP - The TX DSP is a TI OMAP Multimedia Processor. The OMAP1710 consists of a microprocessor unit (MPU) subsystem and a digital signal processor (DSP) subsystem. OMAP1710 has dedicated external memory interface that allow point-to-point connection to standard mobile SDRAM/DDR and mobile flash devices. It is a low-power device (1.4V Core and 1.8V I/O supply). TX OMAP handles all transmit tasks of the SCM. External Memory - Both transmit and receive DSP’s support independent external memory banks. RAM - The SCM supports Mobile Double Data Rate SDRAM. It has the following basic characteristics: The maximum external clock rate for the DDR is 90 MHz. Since data is transferred on both clock edges, the effective data rate is 180 Mwords/s. Flash - The SCM supports 256 MB external flash memory. Serial Peripheral Interface (SPI) - The station local and Intermodule SPI Bus is controlled by both TX and RX OMAP1710 processors, which has an on-chip SPIF (fast SPI) interface. The OMAP1710 SPIF supports master
APPLICANT: MOTOROLA EQUIPMENT TYPE: ABZ89FC3797 User / Operational Manual Functional Description / Operation of Modules (Draft) EXHIBIT D1-6 and slave modes, programmable clock rate, phase, polarity, programmable word size, programmable bit ordering, and loopback. Before an SPI data transfer can take place, the SPI master (initiator) must assert the select line of the slave (target) device. The OMAP1710 is always the SPI master for MTR3000 BR. To simplify overall SPI architecture for MTR3000 BR, address decoding is used instead of individual device chip signals. This approach not only minimizes the number of GPIOs needed for device chip select, it also provides flexibility for future expansion. This device address decoding is handled by a Field Programmable Gate Array (FPGA) on the SCM and a Customer Programmable Logic Device (CPLD) on each FRU’s, except the power supply. The FPGA SPI module performs address and chip select decoding, level shifting, and signal mixing for both the TX OMAP SPI bus and the RX OMAP SPI bus. Simultaneous RX and TX SPI accesses are allowed. The TX and RX SPI are 100% independent. Station Reference RX - A TCXO provides the frequency reference for the BR. The TCXO is 16.8 MHz. The FPGA is used to create other clocks locked to the TCXO which are needed by various devices on the Control Board. The clocks are summarized in the following table: Station Control Module (SCM) FPGA output Frequencies Frequency Destination 12 MHz TX OMAP, RX OMAP 24.576 MHz MAKO 32.768 kHz TX OMAP, RX OMAP, MAKO RX OMAP The RX DSP is a TI OMAP Multimedia Processor. The OMAP1710 consists of a microprocessor unit (MPU) subsystem and a digital signal processor (DSP) subsystem. OMAP1710 has dedicated external memory interface that allows point-to-point connection to standard mobile SDRAM/DDR and mobile flash devices. It is a low-power device (1.4V Core and 1.8V I/O supply). The RX OMAP handles receiving tasks of the SCM only. MAKO - MAKO IC is a customized IC and the SCM uses this device to leverage some unique functionality that it provides. Most of the MAKO functionalities are not used on the SCM. Only the MAKO codec, USB driver, ADC, DAC, and some voltage regulators are used for MTR3000. The 9 channel general purpose ADC is used for various controller metering. Field Programmable Gate Array (FPGA) - The SCM FPGA includes the following major functions: • External reference watchdog • SPI Address decoding and buffering • TCXO Phase detection and compensation • Clock generation • Reset controller • External Interface (Wireline SSI, LED, etc.) FPGA field upgrade capability is also supported on MTR3000. Audio - There are four transmit inputs: TX Audio, TX Audio-Pre & TX Data on the backplane 25-Pin connector, and the microphone input on a front panel RJ45 connector. TX Audio is a flat (not pre-emphasized) input which is used if the incoming transmit audio signal is already pre-emphasized or if pre-emphasis is not needed. The TX Audio-Pre input provides a hardware pre-emphasis filter. The TX Data input is used for low speed data, Private-Line (PL) and Digital Private Line (DPL) signals. The TX Audio, TX Audio-Pre and microphone inputs pass through a hardware modulation limiter and splatter filter before being summed with TX Data, with the TX Data bypassing the limiter and splatter filter. This summed signal is applied to the MAKO codec “mic” input. The audio signal without TX Data is provided on the MAKO codec “aux_mic” input. There are three receive outputs: RX Audio & Aux RX Audio on the backplane 25-Pin connector and speaker audio on a front panel RJ11. The speaker audio is the sum of the MAKO codec output (demodulated audio) and transmit audio. A high pass filter removes any data, PL or DPL from the speaker audio. A programmable attenuator is used to adjust the speaker audio level before being output on the RJ11 connector. Aux RX Audio is the output of
APPLICANT: MOTOROLA EQUIPMENT TYPE: ABZ89FC3797 User / Operational Manual Functional Description / Operation of Modules (Draft) EXHIBIT D1-6 the MAKO codec (demodulated audio), and RX Audio is the sum of the MAKO codec output and the microphone audio. A block diagram of the audio paths follows: Ethernet Interface - Since OMAP1710 does not support a direct Ethernet interface, a bridge device is needed to support Ethernet on the SCM. The bridge device is a high performance hi-speed USB2.0 to 10/100 Ethernet controller. The device contains an integrated 10/100 Ethernet PHY, USB PHY, Hi-Speed USB 2.0 device controller, 10/100 Ethernet MAC, TAP controller, EEPROM controller and a FIFO controller with a total of 30 KBytes of internal packet buffering. The following is a list for functionality that the Ethernet Interface can provide: • Fully Compliant with IEEE 802.3 and 802.3u Compatible Ethernet Controller • 10Base-T and 100Base-TX support • Integrated Media Access Control (MAC) and PHYsical (PHY) • Supports one 10BT port with automatic polarity detection and correction • Supports full and half duplex mode and flow control • Universal Serial Bus (USB) and Joint Test Action Group (JTAG) parameters Backplane - The connector that connects the controller to the backplane is a right angle, 96-Pin Connector. It provides connectivity between the MTR3000 controller and other station FRU, such as the Wireline card, the AUX IO card as well as, third party equipments. Exciter - The connector used to connect the controller to the Exciter and Receiver is a dual row, right angle, early entry receptacle, without flange, 30-Pin Connector. It provides 16.8 MHz reference clock, 14.2V, 10V and 8V supply voltage, SPI, Trident SSI and other digital handshake signals with the Exciter.

The signal is then low-pass filtered, and the 1/2 IF and image frequency are filtered through the tunable preselector. This signal is then amplified using a low-noise amplifier (LNA), and then further filtered to remove the image signal. Receiver Back End Circuitry The signal after the image filter is then mixed down to the first IF, via a high performance (high IIP3) mixer, driven by the low-phase noise, voltage-controlled Colpitts oscillator (VCO). The mixed-down signal then passes through a 3-pole, crystal IF bandpass filter and an IF amplifier. The amplifier output signal passes through another 3-pole crystal bandpass filter, and the resultant signal passes through a digital step attenuator. The desired signal is then applied to the RF input of the custom backend Receiver IC. Voltage Controlled Oscillator (VCO) The Receiver Voltage Controlled Oscillator (VCO) generates a sinusoidal output signal that ranges from 180.85 MHz to 218.85 MHz. The Receive Voltage-Controlled Oscillator (RXVCO) line-up consists of four sub-circuits: a Voltage-Controlled Oscillator (VCO), an attenuator, a buffer-amplifier, and a low pass filter (LPF). The active device is from oscillator topology, utilizing a high-Q resonator, and four anti-parallel configured, hyper-abrupt, tuning varactors. The attenuator provides a broadband RF load for the VCO. The buffer-amplifier provides power leveling and isolation. The LPF provides VCO harmonic attenuation. Synthesizer Circuitry The Receiver synthesizer is a subcircuit within a custom IC, which when connected with a loop filter, VCO, buffer amplifier, lowpass filter, driver amplifier, unequal splitter, and feedback attenuator forms a phase-locked loop. The frequency and phase of the VCO is locked to a highly-stable external Temperature Compensated Crystal Oscillator (TCXO) reference (16.8 MHz). The custom IC contains the following integrated Phase locked loop (PLL) components: prescaler, fractional-N divider, reference divider, phase detector, and charge-pump (for the external loop-filter). The reference divider frequency is selected depending on the frequency band of operation, and will range from 3.36 MHz to 16.8 MHz.

The second IF signal is converted to a digital signal, and output via either a differential or single-ended driver to the digital signal processor (DSP) in the SCM. Memory Circuitry The memory circuitry consists of an Electrically Erasable Programmable Read-Only Memory (EEPROM), located in the Receiver. The SCM performs memory read and write operations via the SPI bus. The RX Front-End Filter tuning calibration is stored in the EEPROM. Therefore, no field tuning is ever required for the Receiver. Analog to Digital (ADC) Converter Metering Circuitry Analog signals from points throughout the Receiver are applied to the ADC converter. These analog signals are converted to digital signals and then sent to the SCM, via the Serial Peripheral Interface (SPI) lines, upon request of the SCM. Communications with Station Control Module Data communications between the Receiver and the Station Control Module microprocessor (μP) is performed via a Serial Peripheral Interface (SPI) bus. This bus allows the SCM μP to send data to the synthesizer PLL IC (to select frequency) and to read the ADC Converter IC. ADC Converter Circuitry Analog signals from various strategic operating points throughout the Receiver board are fed to an ADC converter, which converts them to a digital signal and, upon request by the Station Control Module, outputs the signal to the Station Control Module via the Serial Peripheral Interface (SPI) bus.

Contained within a metal clamshell housing, the Exciter board generates a low-level modulated Radio Frequency (RF) signal which is input to the power amplifier module for further amplification and output to the transmit antenna. The Exciter Modules interfaces directly with the Station Control Module (SCM), which provides control signals and monitoring, and routes transmit audio to the Exciter. The RF carrier is generated by a frequency synthesizer consisting of synthesizer circuitry and Voltage-Controlled Oscillator (VCO) circuitry. Exciter module control signals, monitoring, and audio processing are handled by the Station Control Module (SCM). The Exciter board contains the following circuitry: • Frequency Synthesizer Circuitry – consists of a phase-locked loop and Voltage-Controlled Oscillator (VCO), generates a modulated RF signal at the transmitter carrier frequency • RF Isolation Switch – allows the SCM to turn on/off the Exciter RF output signal to the power amplifier module • Analog to Digital Converter (ADC) Converter Circuitry – converts the analog Exciter status signals to the digital format for transfer, upon request, to the SCM • Local Power Supply Regulation/Filtering – accepts +8V, +10V and +14.2V inputs and provides +5V, +10V, and +12V operating voltages • Low Level Amplifiers – amplify and buffer the modulated RF signal from the VCO for delivery to the power amplifier module Input and Output Connections - The following shows the Exciter module input and output external connections.

APPLICANT: MOTOROLA EQUIPMENT TYPE: ABZ89FC3797 User / Operational Manual Functional Description / Operation of Modules (Draft) EXHIBIT D1-6 Functional Theory of Operation The following theory of operation describes the operation of the Exciter circuitry at a functional level. The information is presented to give the service technician a basic understanding of the functions performed by the module in order to facilitate maintenance and troubleshooting to the module level. Refer to a block diagram of the Exciter module. Functional Overview Synthesizer and VCO Circuitry Phase-Locked Loop The phase-locked loop (PLL) IC receives frequency selection data from the SCM microprocessor (via the SPI bus). Once programmed, the PLL IC compares a reference frequency signal with a divided-down feedback sample of the VCO output. The reference frequency is selected depending on the frequency band of operation, and will range from 3.36 MHz to 16.8 MHz. Depending on whether the feedback signal is higher or lower in frequency than the reference, up/down correction pulses are generated. The width of these correction pulses depends on the quantitative difference between the reference and the VCO feedback. The up/down pulses from the PLL IC are fed to a charge pump which outputs a DC voltage proportional to the pulse widths. This DC voltage is then low-pass filtered and fed to the VCO as the control voltage. Voltage Controlled Oscillator (VCO) The DC control voltage from the synthesizer is fed to dual VCOs which generate the RF carrier signal. Within each band, one VCO generates signals in the upper half of the band, while the other VCO generates signals in the lower half of the band. Only one VCO is active at a time. Selection of the active VCO is provided by a VCO_SELECT signal from the PLL IC. The active VCO responds to the DC control voltage and generates the appropriate RF signal. This signal is fed through impedance matching, amplification, and filtering and is output to the RF Switch Circuitry. A sample of the output is returned to the PLL IC to serve as a VCO feedback signal. Modulation The Exciter uses dual-port FM modulator consisting of Digital Signal Processor (DSP), PLL low-port and high port blocks, fractional-N PLL, loop filter and the VCO. The modulator is calibrated once during factory test and its values are stored in the EEPROM. The modulator does not require any further tuning or maintenance. Amplifiers The amplifiers consist of a driver amplifier and the final amplifier. The driver amplifier operates from a nominal 5V supply and the final amplifier operates from a nominal 10V supply. The driver amplifier amplifies the VCO output signal and provides the output signal to the final amplifier. There are fixed attenuators at the output of the driver and final amplifier to set the Exciter output power level. The final amplifier amplifies the signal and provides a constant signal level to the PA. RF Switch Circuitry The modulated RF signal from the VCO is fed through a buffer, driver, and attenuator and finally to an RF switch circuit. Signal EX_ENABLE from the SCM controls the switch and final amplifier. The RF signal is passed through a LPF and to a BNC connector mounted in one corner of the module, just outside the module cover. A short coaxial cable connects the Exciter output to the power amplifier module.

Voltage Regulation/Filtering Circuitry The voltage regulator circuitry consists of a +5V, +3.3V and +2.775V regulators that supplies power to the digital circuitry and the PLL. The +12V regulator is used to supply power to the VCO and the +10V supplies power to the final device.
APPLICANT: MOTOROLA EQUIPMENT TYPE: ABZ89FC3797 User / Operational Manual Functional Description / Operation of Modules (Draft) EXHIBIT D1-6 Power Amplifier Module Overview The Power Amplifier (PA) is a forced convection-cooled RF power amplifier. It accepts a low-level modulated RF signal from the Exciter Module and amplifies the signal for transmission via the site transmit antenna. The output power is continually monitored and regulated by a feedback and control loop, with a power output control voltage being generated by the transmitter control circuitry located on the PA Input/Output boards. Overview of Circuitry The Power Amplifier contains the following sub-circuits: • Intermediate Power Amplifier (IPA) – hybrid substrate amplifier stage which accepts low-level input from Exciter Module, amplifies the signal, and outputs a 0 W to 10 Watt RF signal • Final Module – hybrid substrate amplifier stage which accepts output from IPA Hybrid and provides final amplification to 40 Watts (maximum) • Directional Coupler/Power Detector/Low Pass Filter – couples amplified RF signal to transmit antenna connector; also generates dc voltages proportional to forward and reflected power for use in TX power control loop; provides harmonic suppression for the station • Single Circulator – provides isolation between Power Amplifier output and transmit antenna • Temperature Sense Circuitry – provides variable resistance signal proportional to heat sink temperature; signal is monitored by the PA power control circuitry Input and Output Connections The following shows the PA input and output external connections.
APPLICANT: MOTOROLA EQUIPMENT TYPE: ABZ89FC3797 User / Operational Manual Functional Description / Operation of Modules (Draft) EXHIBIT D1-6 The following table shows the specifications of MTR2000 Power Amplifier (PA). Specifications of Power Amplifier Parameter Specification Operational Frequency Range 136–174 MHz Minimum Input Return Loss (TX mode) 10 dB Rated RF Output Power Range 1–40 W Rated RF Input Power Range 11.8–16 dBm 14.2V Supply Nominal Voltage 14.2V (+/- 3%) 14.2V Supply Maximum Current Draw 9.0A Maximum Standby Power Consumption 1.5 W Functional Theory of Operation A low-level modulated RF signal (approximately +13 dBm) from the Exciter Module enters the PA Input board via a coax cable. The signal is input to the IPA and amplified to approximately 0 to 10 W (depending on the dc power control voltage (V_CNTL) from the PA output board). The IPA output is then fed to the Dual Device Module for further amplification. The output of the DDM is then transferred to the circulator and then to the harmonic filter/coupler via the PA output board. The signal then exits from the Power Amplifier Module via an N-type coax connector. A single circulator is built into the Power Amplifier Module to provide isolation between the PA module and the transmit antenna. A thermistor mounted on the PA printed circuit board outputs a variable resistance proportional to the heat sink temperature. This signal is fed to the power control circuitry on the PA output board, which monitors the signal and reduces the PA output power (and enables a fan) if the PA temperature exceeds set limits. A feedback and control loop configuration is used to regulate the PA output power. The Directional Coupler generates a dc voltage proportional to the PA Module output power. This voltage is fed to power control circuitry on the PA output board where it is compared to reference voltages to generate a dc power control voltage. The Station Control Module sends current and power limit signals to a D/A converter (via the SPI bus) to control the maximum current/control voltage levels. The control voltage is fed to the IPA module where it controls the IPA output, thus controlling the overall output from the PA Module. Analog signals from various strategic operating points throughout the PA module are fed to an A/D converter, which converts them to a digital signal and, upon request by the Station Control Module, outputs the signal to the Station Control Module via the SPI bus. For example, the directional coupler generates a dc voltage proportional to the reflected power. This signal is converted to a digital signal and sent to the SCM. If the sense line indicates an impedance mismatch (high VSWR), the PA is either cut back in power or shut down completely.
APPLICANT: MOTOROLA EQUIPMENT TYPE: ABZ89FC3797 User / Operational Manual Functional Description / Operation of Modules (Draft) EXHIBIT D1-6 Power Supply Module Overview The Power Supply is described in this section. The information provided is sufficient to give service personnel a functional understanding of the module, allowing maintenance and troubleshooting to the module level. Refer to the service manual for Maintenance and Disassembly/Reassembly Procedures for detailed removal or installation procedures for all modules in the station. Over-current conditions on either the 28.6 VDC or 14.2 VDC outputs cause the total supply to shutdown and try to restart. If the over-current continues to exist, the power supply will ‘hiccup’ until the overload condition is removed, and will not be damaged by the overload. The 28.6 VDC output is protected by a primary current sense method such that its current limit point varies depending on the load on the other outputs at the time. The trip point for the 14.2 V and 5.1 V outputs is greater than 115% of the maximum current specified for the outputs. The power supply recovers automatically after the removal of the overload condition. The 28.6 V and 14.2 V outputs are protected from continuous over-voltages by detection circuits that cause the supply to shutdown and then try to restart itself. If the over-voltage condition continues to occur, the supply goes into a ‘hiccup’ mode of shutting down and trying to restart. If the over-voltage condition is removed, the supply automatically recovers. In addition, the 14.2 V and the 5 V outputs are protected by crowbar circuits. An AC Fail detect signal is provided to indicate (when used with battery backup option) that the power supply is operating from an external dc source rather than the ac mains. This signal is a TTL compatible output capable of sinking 1 mA, and is routed to the Station Control Module. The active-low state indicates ac operation. For the nominal 120 VAC operation, the signal is active-high impedance (indicating an ac mains failure) when the ac voltage is less than 85 Vrms, but more than the minimum voltage that guarantees that all outputs will be in regulation at full load. For the nominal 240 AC operation, the detect point is less than 170 Vrms but more than the minimum ac input voltage that guarantees that all outputs be in regulation at full load. The supply incorporates temperature sense/fan enable circuitry for controlling a 12VDC fan mounted on the surface of the heatsink assembly. The power supply circuitry senses the internal temperature of the power supply. When the internal temperature exceeds +60°C (± 5°C), +12 V is enabled at J1–1 to turn on the fan. The +12 V fan supply is derived from the +14.2 V output. Power to the fan is off when the temperature is below the set limit. The fan turns for approximately 5 seconds when power is first applied as a diagnostic indicator that the fan is functional. The power supply will turn off all outputs when an operational ambient temperature of +80°C (±2°C) has been reached with the supply operating at any input within its operating input voltage range (dc and ac). The following shows the electrical performance specifications for the power supply.
