4 FREQUENCY PROGRAMMING
Frequency Programming
Channel and tone frequency programming is most easily accomplished with RF
Technology TecHelp/Service Monitor 2000 software. This software can be run on
an IBM compatible/Windows PC and provides a number of additional useful
facilities.
TecHelp/Service Monitor 2000 allows setting of the adaptive noise squelch
threshold, provides a simple means of calibrating the signal strength output and
minimum signal alarm.
TecHelp/Service Monitor 2000 can be supplied by your dealer, distributor or by
contacting RF Technology direct.
Circuit Description
The following descriptions should be read as an aid to understanding the block and
schematic diagrams at the rear of this manual.
5.1
RF Section
A two pole voltage tuned filter (D13, D14, L35-39) is used to limit the RF band
width prior to the RF amplifier transistor Q1. The tuning voltage is supplied by the
frequency synthesizer through voltage follower U28D. The circuit values are chosen
so that the centre frequency tracks the VCO frequency.
RF amplifier transistor Q1 is followed by a second two pole voltage tuned filter
(D15, D16, L28-32) which provides additional image and spurious frequency
rejection. The filter output is connected to the RF input port of the mixer MX1.
MX1 is a high level double balanced diode ring mixer with excellent intermodulation
performance. It has a conversation loss of approximately 6 dB. The gain between
the receiver input and the mixer input is approximately 10 dB so that the total gain
between the antenna input and the IF input 3-4dB.
Monolithic amplifiers MA1, MA2 and transistor Q5 amplify the VCO output to the
necessary LO level for MX1 approximately +13dBm.
The network C8, C9 L1-3 and R6 passes the IF frequency of 45 MHz and terminates
the RF and LO components.
5.2
IF Section
The first IF amplifier uses two parallel connected JFET transistors Q2 and Q3 to
obtain 8-10 dB gain. The two transistors provide improved dynamic range and input
matching over a single transistor.
Page 12
RF Technology R220

CIRCUIT DESCRIPTION
5.2 IF Section
A two pole 45 MHz crystal filter XF1 is used between the first and second IF
amplifiers. The second IF amplifier Q4 provides additional gain of 6-10dB. A two
pole crystal filter is used between Q4 and the 2nd oscillator mixer. These two crystal
filters provide some adjacent channel rejection and all of the second IF image
frequency rejection.
U1 is a monolithic oscillator and mixer IC. It converts the 45 MHz IF signal down to
455 KHz. The second oscillator frequency or 45.455 MHz is controlled by crystal
Y1. The 455 KHz output of the second mixer is fed through a ceramic filter CF1 to
the second IF amplifier transistor Q27. Q27 provides an additional 15 dB gain ahead
of the limiter and discriminator IC U3.
The limiter/discriminator IC U3 further amplifies the signal and passes it through
CF2. CF2 does not contribute to the adjacent channel rejection but is used to reduce
the wide band noise input to the limiter section of U3.
The limiter section of U3 drives the quadrature detector discriminator. C31 and IF
tuned circuit L10 comprise the discriminator phase shift network.
U3 also has a received signal strength indicator output (RSSI). The RSSI voltage
connects to the test socket for alignment use. The RSSI voltage is also used by the
microprocessor for the adaptive noise squelch, carrier squelch and low signal alarm
functions.
Dual op-amp U2 is used to amplify and buffer the discriminator audio and RSSI
outputs.
5.3
VCO Section
The Voltage Controlled Oscillator uses a junction FET Q6 which oscillates at the
required mixer injection frequency. Varactor diode D4 is used by the PLL circuit to
keep the oscillator on the desired frequency. Transistor Q7 is used as a filter to
reduce the noise on the oscillator supply voltage.
5.4
PLL Section
The synthesizer frequency reference is supplied by a temperature compensated
crystal oscillator (XO1). The frequency stability of the oscillator is better than 1
ppm.
The 12 MHz output of Q25 or XO1 is amplified by Q8 to drive the reference input
of the PLL synthesizer IC U4. This IC is a single chip synthesizer which includes a
1.1 GHz pre-scaler, programmable divider, reference divider and phase/frequency
detector. The frequency data is entered a serial data link from the microprocessor.
The phase detector output signals of U4 are used to control two switched current
sources. The output of the positive and negative sources' Q10 and Q16, produce the
tuning voltage which is smoothed by the loop filter components to bias the VCO
varactor diode D4.

5.5 Audio Signal Processing
5.5
5 CIRCUIT DESCRIPTION
Audio Signal Processing
A 4 KHz low pass filter (U27b) is used to remove high frequency noise from the
signal. A 300 Hz high pass filter (U26a,b) then removes the sub-audible tones. A 240
Hz notch filter (U26c,d) is used to improve the rejection of tones above 200 Hz. The
high pass and notch filters can be bypassed by internal jumpers JP1 and JP3.
The audio frequency response can be set for either 750 uS de-emphasis or a flat
characteristic by JP2. JP2 selects the feedback network of amplifier U27c.
After de-emphasis and filtering, the audio signal is applied to the inputs of two
analog switches (U17a,b). These switches are controlled by the micro-controller and
squelch or mute the audio to the line and monitor output circuits. The monitor output
can be set for noise squelch only operation by S1.
The audio from U17a is adjusted by the volume control before connecting to the
monitor output amplifier U5. U5 drives the internal speaker and can also supply 3-5
watts to an external loudspeaker.
The audio from U17b is adjusted by RV3 before connecting to the line output IC
(U22a,b). U22 is a dual amplifier connected in a bridge configuration to drive the
600Ω line output transformer T1.
5.6
Noise Filter, Amplifier and Detector
The unfiltered audio from the discriminator is fed to trimpot RV4 which is used to
set the noise squelch threshold. From RV4 the audio goes to the noise filter (U27a).
This is a 10 KHz high pass filter and is used to eliminate voice frequency
components.
The noise signal is then amplified by U27d and fed to the noise detector. The noise
detector consists of D6, Q17 and U26c. D6 and Q17 are a charge pump detector and
pull the input to U26c low as the noise increases. U26c has positive feedback and
acts like a schmitt trigger. The output of U26c goes high when noise is detected. It
connects to the micro-controller and to analog switch U17d. U17d varies the gain of
the noise amplifier to provide approximately 2dB hysteressis.
5.7
Sub-Tone Filter and CTCSS
The discriminator audio is fed through cascaded low pass filters U28a and U28b to
filter out the voice frequency components. The filtered sub-tone audio is supplied to
the CTCSS hybrid and the rear panel system connector. The filtered output can be
used for re-transmission of CTCSS or DCS.
The CTCSS decoder module is a micro-controller base hybrid module. Under control
of the main microprocessor U15 it can decode all 38 EIA tones and 12 additional
commonly used tones. The decode bandwidth is set to 1% but may be changed to 2%
by a jumper on the printed circuit board.
Page 14
RF Technology R220

5.8
CIRCUIT DESCRIPTION
5.8 External Squelch
External Squelch
The audio output can be muted through pin 8 of the receiver system connector P1.
When pin 8 is pulled to less than 1 volt above ground, the micro-controller U15 will
mute the audio output.
This facility can be used to mute the audio during transmission, as is required in
single frequency systems, by simply connecting pin 8 of the receiver to the
transmitter T/R relay driver output (pin 16 on Eclipse transmitters).
5.9
Microprocessor Controller
The microprocessor controller circuit uses an advanced eight bit processor and
several support chips. The processor U15 includes EE memory for channel
frequencies, tones, and other information. It also has an asynchronous serial port and
an analog to digital converter.
The program is stored in U12, a CMOS EPROM. U13 is an address latch for the low
order address bits. U11 is used to read the channel select lines onto the data bus. U7
is an address decoder for U11 and U12. U14 is a supervisory chip which keeps the
processor reset unless the +5 Volt supply is within operating limits. U16 translates
the asynchronous serial port data to standard RS232 levels.
The analog to digital converter is used to measure the received signal strength, tuning
voltage, dc supply voltage and the carrier squelch setting.
5.10
Carrier Operated Switch
The carrier operated switch is an opto-coupled (ISO1) output. Internal jumpers
(JP4,7,8,9) can be connected to provide loop source, loop switch, free switch and
various other configurations.
The COS can be set to be active (switch closed) on carrier or active in the absence of
carrier.
The generic term ``Carrier Operated Switch'' may be misleading in this case. SINCE,
if a sub-audible tone has been programmed for the channel in use, the COS is
controlled by carrier and tone detection.

5.11 Voltage Regulator
5.11
5 CIRCUIT DESCRIPTION
Voltage Regulator
The dc input voltage is regulated down to 9.4 Vdc by a discrete regulator circuit. The
series pass transistor Q20 is driven by error amplifiers Q21 and Q22. Q23 is used to
start up the regulator and once the circuit turns on, it plays no further part in the
operation.
This circuit is short circuit and overload protected. It provides much better line
isolation and lower dropout voltage than can be obtained with current integrated
circuit regulators.
Alignment Procedure
The following procedures may be used to align the receiver for optimum
performance. Normally only RF alignment will be required when changing
frequencies. IF alignment should only be necessary after repairs on that part of the
circuit.
Reference oscillator or TCXO calibration may be required periodically due to crystal
aging. The aging should be less than 1 ppm/year.

Specifications
7.1
General Description
The receiver is a high performance, frequency synthesized, narrow band FM unit
which can be used in conjunction with transmitter and power supply modules as a
base station or as a stand alone receiver. All necessary control and 600Ω line
interface circuitry is included.
7.1.1
Channel Capacity
Although most applications are single channel, it can be programmed for up to 100
channels numbered 0-99. This is to provide the capability of programming all
channels into all of the receivers used at a given site.
7.1.2
CTCSS
The CTCSS tone or no tone can also be programmed for each channel. So that each
channel number can represent unique RF and tone frequency combination.
7.1.3
Channel Programming
The channelling information is stored in a non-volatile memory chip and can be
programmed via the front panel test connector using a PC and RF Technology
supplied TecHelp/Service Monitor 2000 software.

7.1.4
SPECIFICATIONS
7.1.4 Channel Selection
Channel Selection
Channel selection is by eight channel select lines. These are available through the
rear panel connector.
A BCD active high code applied to the lines selects the required channel. This can be
supplied by pre-wiring the rack connector so that each rack position is dedicated to a
fixed channel.
BCD switches inside the receiver can be used to pre-set any desired channel. These
eliminate the need to externally select the channel.
7.1.5
Microprocessor
A microprocessor is used to control the synthesizer and squelch functions and
facilitate the channel frequency programming. With the standard software it also can
provide fault monitoring and reporting.
7.2
Physical Configuration
The receiver is designed to fit in a 19 inch rack mounted frame. The installed height
is 4 RU (178 mm) and the depth 350 mm. The receiver is 63.5 mm or two Eclipse
modules wide.
