SECTION 2 INSTALLATION
2.1 I’M-INSTALLATION CIECKS
Field alignment should not be required before the
3474 is inmlled. However, it is still good practice to
check the performance to ensure that no damage
occurred during shipment. Performance tests are
locamd in Section 6.2.
2.2 INTERFACWG WITH DATA EQUIPMENT
2.2.1 DMJ474 ONLY
Connector 1201 on the data transceiver PC hoard
provides the interface with the data equipment. This is
a l4-pin female connector with .025" square pins on
0.1 " centers (Dupont 76308-1 14). An interface cable
diagram and pin designations are shown in Figure 2-1.
This cable is not included with the data transceiver.
The following is a general description of the vari-
ous J201 input and output signals.
Pin 1 (Ground) - Chassis ground.
Pin 2 (+7.5V DC Continuous) . This voltage should
be stabilized near +7.5V DC, Variations from +6V to
+9V can change power output as much as 6 dB.
Pin 3 (+7.SV DC Transmit) - This input should be
+7.5V DC in transmit mode only.
Pin 4 (+5V DC Reoeive Control line) - This input
should be +5V DC in the receive mode only, 5 0.3 V
DC in Tx, input impedance 2 10k ohms.
Pin 5 (+5V DC Continuous) - This voltage should be
stabilized near +5V DC.
Pin 6 (Tx Input) - Provides a response of ti .5 dB from
DC to 5 kHz. The sensitivity is approximately 7 kHz
deviation pervolt RMS. When this input is used, a
temperature compensated 2.5V DC bias is required be-
cause variations in voltage cause the frequency to
change. In addition, the transceiver regulatory compli-
ance must be applied for with the customer supplied
modulation limiting/filter circuit and chassis.
Pin 7 (Synthesizer Lock) - Output from synthesizer
lock depot circuit. Low = unlocked, high = locked.
Pin 8 (Synthesizer Enable) - Latch enable signal. A
rising edge on this input latches the data loaded into
synthesizer 1C USO].
Pin 9 (Synthesizer Data) - Serial data line used for
programming synthesizer lC USO].
Pin 10 (Synthesizer C10ek)~ Software generated seri-
al clock. Data is valid on the rising edge of this signal.
Pin 11 (Currier Detect) - This output is not used atthis
time.
Pin 12 (R881 Output) - The RSSl (Receive Signal
Strength Indicator) output provides a voltage that in-
creases in proportion to the strength of the RF input
signal.
Pin 13 (Rx Output) » The data output level is 600-
l200 rnillivolts P-P (200-400 mV RMS) with a modu-
lation signal of 1 kHz at 60% ofmaximum deviation.
The output is DC coupled and referenced to +2.5V DC.
Load impedance should be lOk—lOOk ohms.

SECTION 4 CIRCUIT DESCRIPTION
4.1 GENERAL
4.1 .1 INTRODUCTION
The main subassemblies of this transceiver are
the RF board, VCO board, TCXO. A block diagram
ofthe transceiver is located in Figure 4-1.
The VCO board is enclosed by a metal shield and
soldered directly to the RF board. The VCO is not
serviceable.
The 3474 is available with a reference oscillator
stability of 11.5 PPM. The TCXO (Temperature
Compensated Crystal Oscillator) is soldered directly
to the RF board.
4.1 .2 SY'NTHESlZER
The VCO (Voltage-controlled oscillator) output
signal is the receiver first injection frequency in the
Receive mode and the transmit frequency in the
Transmit mode. The first injection frequency is 52.95
MHz above the receive frequency. The frequency of
this oscillator is controlled by a DC voltage produced
by the phase detector in synthesizer chip U801.
Channels are selected by programming counters
in USO] to divide by a certain number. This program-
ming is performed over a serial bus formed by the
Synth Clock, Synth Enable, and Synth Data pins of
1201. This programming is performed by user sup-
plied hardware and sofiware (see Section 3).
The frequency stability of the synthesizer in both
the receive and transmit modes is established by the
stability of the reference oscillator described in the
preceding section. These oscillators are stable over a
temperature range of-30" to +60° C (-22° to +l40° F).
4.1.3 RECEIVER
The receiver is a double-conversion type with
intermediate frequencies of 52.95 MHz / 450 kHz.
Two helical bandpass filters reject the image, half IF,
injection, and other unwanted frequencies. A four»
pole crystal filter enhances receiver selectivity
441.4 TRANSMITTER
The transmitter produces a nominal RF power
output of 2W adjustable to 500 mW (-XXO) or 500
mW adjustable to 75 mW (with Low Power Kit). Fre-
quency modulation of the transmit signal occurs in the
synthesizer. Transmit audio processing circuitry is
contained in the customersupplied equipment.
4.2 SYNTHESIZER
4.2.1 INTRODUCTlON
A block diagram of the synthesizer is shown in
Figure 4-1 and a block diagram of Synthesizer 1C
U801 is shown in Figure 4-2. As stated previously,
the synthesizer output signal is produced by a VCO
(voltage controlled oscillator). The VCO frequency
is controlled by a DC voltage produced by the phase
detector in Ullol. The phase detector senses the phase
and frequency of the two input signals and causes the
VCO control voltage to increase or decrease if they
are not the same. The VCO is then "locked" on fre-
quency.
Programming of the synthesizer provides the data
necessary for the internal prescaler and counters. One
input signal is the reference frequency. This frequency
is produced by the 1745 MHz reference oscillator
(T CXO). The other input signal is the VCO
frequency.

PROGRAMMING
The Fractional-N increment (NF) is a 3~bit word
that is channel dependent. NF is used to program the
sub-channels below the 50 kHz Loop Reference fre—
quency. FCM = 50 kHz and if FMOD = 8, then the
chtional-N increment is: 50 kHz + 8 = 6.25 kHz
To program an 18.75 kHz channel:
NF=18.75 kHz+6.25 kHz

4.2.2 VOLTAGE-CONTROLLED OSCILLATOR
QscilletaLcQBiO)
The VCO is formed by Q850, several capacitors
and varactor diodes, and a ceramic resonator. It oscil-
lates at the transmit frequency in transmit mode and
first injection frequency in the receive mode (approxi-
mately 450 MHz in transmit and 500 MHz in receive).
Biasing of 0850 is provided by R862, R867 and
R868. An AC voltage divider formed by C859, C861
and C862 initiates and maintains oscillation and also
matches 0850 to the tank circuit. The ceramic resona-
tor is grounded at one end to provide shunt inductance
to the tank circuit.
4-3
Emmnqxcontmlandflodulatinn
The VCO frequency is controlled in part by DC
voltage across varactor diodes CR854, CRBSS, CR856
and CR85 I. As voltage across a reverse-biased varac-
tor diode increases, its capacitance decreases. There—
fore, VCO fi'equency increases as the control voltage
increases. CR854/CR855 and CRBSG/CRSSI are par-
alleled varactors to divide the capacitance and
improve Iiniarity, The varactors are biased at -2V to
adjust to the voltage output of USO] . The control line
is isolated from tank circuit RF by choke L851 and
L854 and decoupling capacitor C854. The amount of
frequency change produced by CR854/CR855/CR856/
CRSSI is controlled by series capacitor C353.

Ifrhz receiver is to be operated or 510-512 Ila-[z (-810), a spurious condition may occur to degrade the
receiver sensitivity 2 to 3 dB. If this degradation is unacceptable, [he synthesizer can be reprogrammed to a com-
parison frequency (FCM of31.25 kHz (so that a multipIe of this would not be 52.95 11012) and a modulus ’\
(FMOD) of 5 with a reference divide (NR) of 560. These parameters place the spurious at harmonics of 3 1.25 kHz
(instead of 50 kHz) outside the parsbarld of the IF fillers where the sensitivity is not degraded.

low impedance to RF; and when it is reverse biased, it
presents a very high impedance. The capacitive leg is
switched in when in transmit and out when in receive.
When 120], pin 4 is high'in receive, (2834 is
turned off, QIO] is turned on and the collector voltage
goes low. A low on the base on102 tums the tran-
sistor on and fire regulated +5.5V on the emitter is on
the collector for the receive circuitry. With a low on
the base of 083] the transistor is off and the collector
is high. With a high on the collector onB31 and a
low on the emitter of Q834, this reverse biases CR850
for a high impedance.
The capacitive leg is formed by C85], CRSSO,
C852 and C376. When 120], pin 4 is low in transmit,
0834 is tumed on and ahigh is on the emitter, 0101 is
turned off and the collector voltage goes high. A high
on the base on102 tnms the transistor offend the
regulated +5.5V is removed from the receive circuitry.
With a high on the base of Q83] the transistor is on
and the collector is low. With a low on the collector
on83I and a high on the emitter of Q834, this for-
ward biases CR850 and provides an RF ground
through C851 and C852/C876 are effectively con-
nected to the tank circuit. This decreases the resonant
frequency of the tank circuit.
4.2.8 SYN’I'I-ESIZER INTEGRATED CIRCUIT
(U801)
lntroductim
Synthesizer chip USO] is shown in Figure 4-2.
This device contains the following circuits: R (refer-
ence), Fmional-N, NMI and NM2; phase and lock
detectors, prescaler and counter programming cir-
cuitry. The basic operation was described in Section
4.2.1.
ChanneLEmgmmming
Frequencies are selected by programming the K
Fractional-N, NM] and NM2 in USO] to divide by a
certain number. These counters are programmed by a
user supplied programming circuit. More infonna~
tion on programming is located in Section 3.
CIRCUIT DESCRIPTION
As previously stated, the counter divide numbers
are chosen so that when the VCO is oscillating on the
correct fi'equency, the VCO—derived input to the phase
detector is the same frequency as the reference oscilla-
tor-derived frequency.
The VCO frequency is divided by the internal
prescalerand the main divider to produce the input to
the phase detector.
4.2.9 DOCK DETEJCT
When the synthesizer is locked on frequency, the
SYNTI-I LOCK output of U801 , pin 18 (1201, pin 7) is
a high voltage. Then when the synthesizer is
unlocked, the output is a low voltage. Lock is defined
as a phase difference of less than ] cycle of the
TCXO.
4.3 RECEIVER CIRCUIT DESCRIPTION
4.3.1 I-EELICAL FILTER (2201), RF AMPLIFIER
(Q201)
Capacitor C201 couples the receive signal from
the antenna switch to helical filter 220]. (The antenna
switch is described in Section 4.4.5.) Z201 is a band-
pass filter tuned to pass only a narrow band of fre-
quencies to the receiver. This attenuates the image
and other unwanted frequencies. The helicals are flac-
tory set and should not be tuned.
Impedmce matching between the helical filter
and RF amplifier Q20I is provided by C203, C204
and L201. Q201 amplifies the receive signal to
recover filter losses and also to increase receiver sen-
sitivity. Biasing for Q20] is provided by R201, R202
and R203; and C208/C209 provide RF bypass. CR20I
protects the base-emitterjunction of 020] from exceSv
sive negative voltages that may occur during high sig4
nal conditions. Additional filtering of the receive sig»
nal is provided by 2202. L202, and C205 provide
impedance matching between 020] and 2202. ResisA
tor R204 is used to lower the Q of L202 to make it less
fiequency selective.

Limiter-Amplifier
The output on24l/Z242 is applied to a limiter-
arnplifier circuit in U241. This circuit amplifies the
450 kHz signal and any noise present; then limits this
signal to a specific value. When the 450 kHz signal
level is high, noise pulses tend to get clipped off by
the limiter; however, when the 450 kHz signal level is
low, the noise passes through. C242, C243 decouple
the 450 kHz signal.

From the limiter stage the signal is fed to the
quadrature detector. An external phaseshifi network
connected to pin 8 shifis the phase of one of the detec-
tor inpus 90° at 450 kHz (all other inputs are
unshified in phase). When modulation occurs, the fre-
quency of the IF signal changes at an audio rate as
does the phase of the shified input The detector,
which has no output with a 90° phase shifi, converts
this phase shifi into an audio signal. L242 is tuned to
provide maximum undistorted output from the detec-
tor. R242 is used to lower die Q of L242. From the
detector the audio and data signal is fed out on pin 9.
Audio/Dag Amplifier
The audio/data output of U241 on pin 9 is fed to
the audio amplifier U261. U261 amplifies the
detected audio/data signal and shifis the DC bias level
to 2.5V. The gain is set at approximately 1.5 by
R261/R262. R263 and R264 provide 1! 1.9V DC ref-
erence bias voltage. The audio output of U261 is
applied to 1201, pin 13.
ReceiveSi alStren Indicator RSSI
U241, pin 13 is an output for the RSS] circuit
which provides a current proportional to the strength
of the 450 kHz IF signal. The voltage developed
across R241 is applied to J201, pin 12.

R854, and decoupling of RF signals is provided by
C852 . Impedance matching with the transmitter is
provided by L501 and C502, and impedance matching
with the receiver is provided by L301, C302.
4.4.2 PRE-DRIVER (Q501), DRIVER (Q521)
Pre—driver 0501 is biased class A by R50] and
R502 and R506. L501 and C502 match 0501 to
0851. C520 and C508 bypass RF from the DC line,
and R503 provides supply voltage isolation. R507 ties
the +7.5V supply to the circuit for high power applica-
n'ons and R508 ties the circuit to +5V for low power
applican'ons. Impedance matching between Q501
and Q521 is provided by L502, L503 and C511. R504
and C504 provide negative feedback to prevent
osciallation.
Driver 0521 is biased nearly Class C by R52]
and R522. Impedance matching with 0541 is pro-
vided by L521, C525, C527, L522 and C526.
4.4.3 -5V POWER CONTROL SUPPLY
The 17.5 MHz from the TCXO is coupled
through C902 to 0901. Bias for 0901 is provided by
R903, R904, R901, R902 and R905. C901 and C903
provide RF decoupling. The amplified signal rectified

Q541 is biased for Class C operation. The output
is matched to the low-pass filter by L541, C552, and
several capacitors. The supply voltage is isolated
from RF by ferrite bead EP54I.
Power control is provided by U542. The 5.5V
transmit supply is passed by U54Z to power adjust
R542. The other end of R542 is the rectified -5V from
090] . This negative voltage is required when low

CIRCUIT DESCRIPTION
The -2V applied to the VCO is derived from the
TCXO frequency that is amplified by Q833, rectified
by CR831 and filtered by C844, C845, C846 and
C847 on the RF board.
The VCO frequency is modulated using a similar
method. The transmit audio/data signal is applied
across varactor diode CR852 which varies the VCO
frequency at an audio rate. Series capacitors C856!
C870 set the amount of deviation produced along with
CR853 and C858. R854 provides a DC ground on the
anodes of CR852/CR853, and isolation is provided by
R852 and C855.
The DC voltage across CR853 provides compen-
sation to keep modulation relatively flat over he
entire bandwidth of the VCO. This compensation is
required because modulation tends to increase as the
VCO frequency gets higher (capacitance of CR854/
CR855/0R856ICR851 gets lower). CR853 also bal-
ances the modulation signals applied to the VCO and
TCXO. An external voltage from 1201, pin 14 can
also adjust the modulation.
The DC voltage applied across CR853 comes
from the modulation adjust control R810. R81 1
applies a DC biasing voltage to CR852; C814 pro-
vides DC blocking; and C818 attenuates AC signals
applied through R81 I. RF isolation is provided by
C858, R853, C817 and R812.
4.2.3 VCO AND REFERENCE OSCILLATOR
MODULATION
Both the VCO and reference oscillator (TCXO)
are modulated in order to achieve the required fre-
quency response. If only the VCO was modulated, the
phase detector in U801 would sense the frequency
change and increase or decrease the VCO control volt-
age to counteract the change (especially at the lower
audio frequencies). If only the reference oscillator
frequency is modulated, the VCO frequency would
not change fag enough (especially at the higher audio
frequencies). Modulating both VCO and reference
oscillators produces a flat audio response. Potentiom-
eter R810 sets the VCO modulation sensitivity so that
it is equal to the reference oscillator modulation
sensitivity.

4.2.4 CASCODE AMPLIFIERS (0851/0352)
Tile output signal on the collector of Q850 is cou-
pled by L861/C864 to buffer amplifier Q851IQ852.
This is a shared-bias amplifier which provides ampli-
fication and also isolation between the VCO and the
stages which follow. The signal is direct coupled
from the collector on852 to the emitter of Q851.
The resistors in this circuit provide biasing and stabili-
zation, and C865 and C866 are bypass capacitors.
4.2.5 AMPLIFIER (Q853)
Amplifier 0853 provides amplification and isola-
tion between the VCO and receiver and transmitter.
C868 provides matching between the amplifiers.
Bias for 0853 is provided by R871, R872 and R874.
inductor L856 and capacitor C873 provide impedance
matching on the output.
4.2.6 VOLTAGE FILTER (Q832)
Q832 is a capacitance multiplier to provide filter-
ing of the 4.6V supply to the VCO. R836 provides
transistor bias and C834 provides the capacitance that
is multiplied. lfa noise pulse or other voltage change
appears on the collector, the base voltage does not
change significantly because of0834. Themfore,
base current does not change and transistor current
remains constant. CR832 decreases the charge time of
C834 when power is turned on. This shortens the
startup time ofthe VCO. C841, C840 and C855 are
RF decoupling capacitors.
4.2.7 vco FREQUENCY SHIFT (£2831)
The VCO must be capable of producing frequen-
cies from approximately 403-56435 MHz to produce
the required receive injection and transmit frequen-
cies. If this large of a shifi was achieved by varying
the VCO control voltage, the VCO gain would be
undesirably high. Therefore, capacitance is switched
in and out of the tank circuit to provide a coarse shifi
in frequency.
This switching is controlled by the TIR pin shifi
on 1201, pin 4, QB} 1/0834 and pin diode CR850.
When a pin diode is forward biased, it presents a vary

5.1.1 PERIODIC CHECKS
This transceiver should be put on a regular main-
tenance scledule and an accurate performance record
maintained. Important checks are receiver sensitivity
and transmitter frequency, modulation, and power out-
put. A procedure for these and other tests is located in
Section 6. It is recommended that transceiver perfor-
mance be checked annually even though periodic
checks are not required by the FCC. During the first
year, make an additional check or two to ensure no
TCXO frequency drilting has banned.
5.1 .2 SURFACErMOUNTED COMPONENTS
A large number of the components used on the
transceiver board are the surface-mounted type. Since
these components are relatively small in size and are
soldered directly to the PC board, care must be used
when they are replaced to prevent damage to the com-
ponent or PC board. Surface-mounted components
should not be reused because they may be damaged by
the unsoldering process.

Schemtic diagrams and component layouts of
the PC boards used in this transceiver are located in

5.2.l NTRODUCTION
When there is a synthesizer malfunction, the
VCO is not locked on frequency. When an unlocked
VCO is detected by the lock detector circuic USO],
pin 18 goes low (OV).
NOTE: The user-supplied circuitry must disable the
transmitter and receiver when an aur—oj-Ioclr condi—
tion is indicated.
When the VCO is unlocked, the fkand fv inpus
to the phase detector are usually not in phase (see Sec-
tion 4.1.2). The phase detector in U801 then causes
the VCO control voltage to go to the high or low end
of its operating range. This in turn cause- the VCO to
oscillate at the high or low end of its fi-equency range.
As shown in Figure 4-1, a loop is formed by
VCO Q850, amplifier Q851/Q852, and the RF [N of
U801. Therefore, if any of these components begin to
malfimction, improper signals appear throughout the
loop. However, correct operation of the counters can
still be verified by measuring the input and output fre-
quencies to check the divide number.
Proceed as follows to check the synthesizer IIO
signals to determine if it is operating properly.
5.2.2 REFERENCE OSCILLATOR
Check the signal at U801, pin 8. lt should be
17.5 MHz at a level ofappmximately 1.5V P-P. lfthe

CIRCUIT DESCRIPTION
The low-pass filter consists of L561, C561, L562,
C562, L563, C563 and L564. The filter attenuates
spurious frequencies oceun'ing above the transmit fre-
quency band. The transmit signal is then fed through
the antenna switch to antennajack 1501.
4.4.5 ANTENNA SWITCH (CR561, CR562)
The antenna switching circuit switches the
antenna to the receiver in the receive mode and the
transmitter in the transmit mode. In the transmit
mode, +7.5V is applied to L565 and current flows

R563. When a diode is forward biased, it presents a
low impedance to the RF signal; conversely, when it is
reverse biased (or not condueting), it presents a high
impedance (small capacitance). Therefore, when
January l996
Part No. 00l-3474-00]
4-8
CR561 is forward biased, the transmit signal has a
low-impedance path to the antenna through coupling
capacitor C568.
C567, L566, and C570 form a discrete quarter-
wave line. When CR561 is forward biased, this quar-
ter-wave line is effectively AC grounded on one end
by C570. When a quarter-wave line is grounded on
one end, the other end presents a high impedance to
the quarter-wave frequency. This blocks the transmit
signal from the receiver. C569 matches the antenna to
50 ohms in transmit and receive.
In the receive mode, no power is applied to L565,
so all the diodes are "off". The receive signal then has
a high-impedance path into the transmitter and a low-
impedance path into the receiver because the quarter-
wave line is not grounded.

ALIGNMENT PROCEDURE AND PERFORMANCE TESTS
6.2.3 LOW POWER ALIGNMENT
1. Connect the test setup shown in Figure 6-1.
2. Load the synthesizer with the center channel
fi'equency.
3. Connect a voltmeter to the junction ofR542/R543.
4. Adjust R542 clockwise for -1.5V DC (tOJV DC).
5. Tune C527 clockwise for maximum power,
6. Tune C553 clockwise for minimum power.
7. Adjust R542 for the required power level.
8. Tune C527 for power balance at frequencies which
are as close as possible to :l-5 MHz from the center
of the channel frequency.
9. Re-udjust R542 for the power level required if
necessary.
10.Munitor the frequency widt a frequency counter and
adjust TCXO (not) for the channel fi'equency
1100 Hz.
6.2.4 MODULATION FLATNESS ALIGNMENT
l. Inject a 220 Hz square-wave tone at approximately
0.35V P-P, biased at 2.5V DC on 1201, pin 6.
2. Transmit into the modulation analyzer and observe
modulation output on the oscilloscope. Set the
modulation analyzer high pass filtering offend no
less than a 15 kHz low pass filter.
3. Adjust R810 for a flat square-wave on the
oscilloscope.
4. lnject a I kHz sine-wave on 1201, pin 6, biased at
2.5V DC, at the level below according to the
bandwidth:
0.200V RMS for 12.5 kHz BW (-X10 Radios)
0.330V RMS for 20.0 kHz BW (-X20 Radios)
0.400V RMS for 25.0 kHz BW (-X30 Radios)
5. Switch on TX Modulation. Set the modulation ana-
lyzer for 3 kHz low pass filtering.
January 1996
Part No. 001-3474—001
6. The transmit deviation should measure between:
ill/11.9 kHz for 12.5 kHz BW (-X10 Radios)
119/110 kHz for 20.0 kHz BW (-X20 Radios)
124/118 kHz for 25.0 kHz BW (vX30 Radios)
7. Set a 0 dB reference on the Audio Analyzer.
8. Input a 100 Hz sine-wave. The level should be
within 11.5 dB of the 1 kHz reference.
9. Remove transmit modulation and unkey the
transmitter.
10. Connect a DC voltmeter at thejunction of R807/
R85 5.
ll.Adjust R855 to 2.10V DC (10.05V DC).
