Centers. If local service is not available, the equip-
mem can he retumed to the factory for repair. How-
ever, it is recommended that you contact the Field Sier—
vice Department before retuming equipment. A
service representative may be able to suggest a solu-
tion to the problem so that retum of the equipment
would not be necessary. if using the toll-free number
in the preceding section, enter "8".
Be sure to ﬁll out a Factory Repair Request Form
{$271 for each unit to be repaired, whether it is in or
out of warranty. These forms are available free of
charge by calling the repair lab (see Section 1.6) or by
"“ “ "Ur/gum“
requesting them when you send a unit in for repair.
Clearly describe the diﬂiculry experienced in the
space provided and also note any prior physical dam-
age to the equipment. Include a form in the shipping
container with each unit. Your phone number and
contact name are very important because there are
times when the technicians have speciﬁc questions
that need to be answered in order to completely iden-
tify and repair a problem.
When returning equipment for repair, it is also a
good idea to use a P0 number or some other refermce
number on your paperwm‘k in case you need to call
the repair lab about your unit, These numbers are ref-
erenced on the repair order in make it easier and faster
to locate your unit in the lab.
Return Authorization (RA) numbers are not nec-
essary unless you have been given one by the Field
Service Department. They require RA numbers for
exchange units. or if they went to be aware ofa spe
ciﬁc problem. If you have been given an RA number,
reference this number on the Factory Repair Request
Form sent with the unit. The repair lab will then con-
tact the Field Service Department when the unit
arrives.

SECTION 2 INSTALLATION
2.1 PRFANSTALLATION CHECKS
Field alignment should not be required before the
3474 is installed. However, it is still good practice to
check the performance to ensure that no damage
oceun-ed during shipment. Performance tests are
located in Section 6.2.
1.2 INTERFACHVG WITH DATA EQUIPMENT
2.2.l DM3474 ONLY
Connector 1201 on the data transceiver PC board
provides the interface with the dam equipment. This is
a I4-pin female connector with 025" square pins on
0.1 " centers (Dupont 76308-114). An interface cable
diagram and pin designations are shown in Figtue 2-1.
This cable is not included with the data transceiver.
The following is a general description of the vari-
ous 1201 input and output signals.
Pin 1 (Ground) A Chassis ground.
Pin 2 (+75V 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 (+75V DC Transmit) . This input should be
+7.5V DC in transmit mode only,
Pin 4 (+5V DC Receive 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 -.t1 5 dB 1
DC to 5 kHz. The sensitivity is approximhtely 7 I
deviation per Volt RMS. When this input 115 used,
temperature compensated 2.5V DC bias is requirci
cause variations in voltage cause the ﬁ'eqtaency to
change. In addition, the transceiver regulatory cor
ance must he applied for with the cunomer suppli
modulation limiting/ﬁlter circuit and chassis.
Pin 7 (Synthesizer Lock) - Output from syynthesi:
lock detect circuit. Low = unlocked, high = locker
Pin 8 (Synthesizer Enable) - Latch enable signal
rising edge on this input latches the data loaded in
synthesizer 1C UBDl.
Pin 9 (Synthesizer Dam) - Serial data line used fl
programming synthesizer IC USO].
Pin 10 (Synthen'zer Clock) - Software generated
a] clock. Data is valid on the rising edge dfthis sir
Pin 11 (Carrier Detect) — This output is not. used at
time.
Pin 12 (RSSI Output) — The RSSI (Receiwe Sight
Strength Indicator) output provides a voltage that ;
creases in proportion to the strength of the RF inpl
signal.
Pill 13 [Rx Output) - The data output level is 600
1200 millivolts P—F (200-400 mV RMS) with a mi
lation signal of 1 kHz at 60% of maximum deviati
The output is DC coupled and referenced to +2.5V.

SECTION 3 PROGRAMMING
3.1 INTRODUCTION
DM3474 - The information in Section 32
describes synthesizer programming protocol. This
information can he used as a basis for designing the
synthesizer programming hardware and software
required.
3.2 DM3474 SYNTHESIZER DATA PROTOCOL
Programming of the dividers and the charge
pumps are performed on a 3-line bus; SYNTH
ENABLE, SYNTH DATA, AND SYNTH CLK. On
initial power up three 34-bit words are required to
load the 3474 Data Transceiver. Aﬁer the initial load,
one 32-bit word can he used to change channels.
The SA7025 Synthesizer 10 uses four address
words; D, C, B and A (see Figure 3-4). The C word is
not used in the 3474. The 24- and 32-bit words con-
tain one or four address hits, depending on the address
hits, the data is latched into registers. When the A-
word is loaded, the data of these temporary registers is
loaded together with the A-word into the work
registers.
312.1 D-WDRD
Re‘fm' to Figure 3-1.
TCXO Reference Frequency is 17.5 NH-lz.
Loop Reference Frequency is 50 kHz.
Reference Divide (NR) : 17.5 MHz + 50 kHz
=350 Decimal or 000010101110 Binary.
The 3474 has frequency resolution of 6.25 kHz
and 10 kHz. When programming 6.25 kHz frequency
resolution use FMOD=8. When programming 10 kHz
frequency resolution use FMOD=5.
Example:
(FCM) + FMOD Z 50 kl-lz+ B = 6.25 kHz
(FCM)+FMOD= 50kHz+ 5 = 10 kHz
Where:
"CM = hoop Reference Frequency
1 ‘OD = Fractional N Modulus
Since FMC is the same for both 6.25 kHz ant
10 kHz the loop dynamics are very similar and the
same loop ﬁlter values can be used.
3.2.2 B-WORD
The B—Word is 24-birs long (see Figure 3-2).
contains the Address, Charge Pump setting factor
(CN), Binary Acceleration factors (CK. CL), and
Prescaler Type (PR).
The Charge Pump Current setting (CN) couI
changed on n channel-by-channel basis for ultima
rejection of the Fraction N spurious responses cli
into the carrier frequency. The 3474 synthesizer
an adjust (R855) for the fractional compensation
rent. The factory preset value will allow CN to 1
to the following ranges:
Frequency in a Band CN
Lowest TX 86
Highest TX 90
Lowest RX 96
Highest RX 100
The value ofCN should be interpolated for
quencies between the hand edgﬁ. With these n
mended values of CN, the transceiver should he
fractional spurs minimized far below the levels I
to make ETSI 70 dB adjacent channel RX or T]

3.2.3 A-WORD
The A-Word must be sent last (see Figure
The A-Word contains new data for the‘loop div

PROGRAMMING
The Fractional-N increment (NF) is a 3-bit word
that is channel dependent NF is used in program the
sub-channels below the 50 kHz Loop Reference fre—
quency. FCM = 50 kHz and ifFMOD = 8, then the
Framional-N incremem is: 50 kHz 4- 8 = 6.25 kHz
To program an 18.75 kHz channel:
NF = 18175111127 6.25 kHz
NF=3

2. The state of the 5RCL line does not have to be
changed until the last bit is sent. However, RX will
cease as soon as it is changed.
3. The SYNTH ENABLE line should he held HIGH
for 2 to 3 milliseconds after the last word is sent.
This puts the frequency synthesizer in a SPEEDUP

4. Aﬁer the last word is seabed in, 7 milliseconds
(worst case) should elapse before 7.5 TX is turned
ON. This allows the synthesizer to come within 1

4.2.2 VOLTAGE-CONTROLLED OSCILLATOR
QscanmﬂQKﬁQ)
The VCO is formed by QSSO, seveml capacitors
and vatacmr 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).
Biesing nf QBSO rs provided by R862, R867 and
R868. An AC voltage divider formed by C359, 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.
WWW
The VCO frequency is controlled in part by
volmgc across veractor diodes CR854, CRSSS, C
and CRBSl. As voltage across a reversahiased '
tor diode increases, its capacitance decreases, Tl
fore, VCO frequency increases as the cone-cl vol
increases. CR854ICR855 and CRSSﬁ/CRSSl an

frequency change produced by CR854/QR855/C
CR851 is controlled by series capacitor (2853.
I __ __ U'H/d'H/kll' __ 11:2
CIRCUIT UbaLlur 1 run
The -2V applied to the VCO is derived from the
TCXO frequency that is ampliﬁed by (2833, 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 Varacllur diode CRBSZ which varies the VCO
frequency at an audio rate. Series capacitors C856/
C370 set the amount of deviation produced along with
CRBS3 and C858. R854 provides a DC ground on the
anodes of CRKSZ/CRSSB, and isolation is provided by
R852 and C855
The DC voltage across CR853 provides compen-
sation to keep modulation relatively ﬂat over the
entire bandwidth of the VCO. This compensation is
required because modulation tends to increase as the
VCO frequency gets higher (capacitance of CR854/
CRESS/CRESSICRSS] 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 CRSSB comes
from the modulation adjust control R810. R811
applies a DC biasing voltage to (311852; C814 pro-
vides DC blocking; and C318 attenuamcs AC signals

C858, R853, C817 and R812
4.2.3 VCO AND REFERENCE OSCILLATOR
MODULATION
Both the VCO and reference oscillator (T CXO)
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 fast enough (especially at the higher audio
frequencies). Modulating both VCO and reference
oscillators produces a ﬂat audio response. Potentiom-
ecer R810 sets the VCO modulation sensitivity so that
it is equal to the reference oscillator modulation
sensitivity.

4.2.4 CASCODE AMPLIFIERS (QSSIIQSSZ)
The output signal on the collector of Q850 is cou-
pled by L861/C864 to buffer ampliﬁer Q851/Q852.‘
This is a shared-bias ampliﬁer which provides ampli-
ﬁcatim‘l and also isolation between the VCO and the
stages which follow. The signal is direct coupled .
from the collector of 0852 to the emitter onBS 1.
The resistors in this circuit provide biasing and stabiliv
zation, and C865 and C866 are bypass capacitors. ‘
4.2.5 AMPLIFIER (9353)
Ampliﬁer 0853 provides ampliﬁcation and isola-
tion between the VCO and receiver and transmitter:
C868 provides matching between the ampliﬁers.
Bias for Q853 is provided by R871, R872 and R874.
Inductor L856 and capacitor 0873 provide impedance
matching on the output.

ing of tire 4.6V supply to the VCO. R836 provides
n-ans‘rsmr bias and 0834 provides the capacitance that
is multiplied. If a noise pulse or other voltage change
appears on the collector, the base voltage does not
change signiﬁcantly because of C834. Therefore,
base current does not change and transistor current
remains constant. CR832 decreases the charge timoof
C334 when power is turned on. This shortens the .
stamp lime ofthe VCO. C841, C840 and C855 arle
RF decoupling capacitors. .
4.2.7 VCO FREQUENCY SHITT(0831)
The VCO must be capable of producing frequen-
cies from approximately 403-56495 MHz to produce
the required receive injection and transmit frequen-
cies. If this large of a shift 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 shift
in frequency.
This switching is controlled by the T/R pin shiﬁ
on JZOI, pin 4, Q83l/Q834 and pin diode CRSSO.
When a pin diode is forward biased, it presents a vary
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 1201, pin 4 is high in receive, Q834 is
turned oﬂ", 0101 is turned on and the collector voltage
goes low. A low on the base onI 02 turns the tran-
sistor on and the regulated +5.5V on the emitter is on
the collector for the receive circuitry. With a low on
the base of Q83l the transistor is off and the collector
is high. With a high on the collector of 0831 and a
low on the emitter of Q834, this reverse biases CR850
for a high impedance.
The capacitive leg is formed by C851, CRRSO,
C852 and C876. When 1201, pin 4 is low in transmit
Q834 is turned on and a high is on the emitter, (Mill is
nirned off and the collector voltage goes high. A high
on the base onlOZ turns the transistor offend the
regulated +5.5V is removed from the receive circuitry.
With a high on the base of Q831 the transistor is on

ward biases CRBSO and provides an RF ground

frequency of the tank circuit.

4.3.1 HELICAL FILTER (2201), RF AMPLIFIE
(0201)
Capacitor C201 couples the receive signal fr
the antenna switch to helical ﬁlter 2201. (The ant
switch is described in Section 4.4.5.) 2201 is a b
pass ﬁlter tuned to pass only a narrow band ofﬁt
quencies to the receiver. This attenuates the imaz
and other unwanted frequencies. The helicals are
tory set and should not be tuned.
Impedance matching between the helical tilt

and L201. 0201 ampliﬁes the receive signal to
recover ﬁlter losses and also to increase receiver
sitiv'ny. Biasing for 0201 is provided by R201, l

CIRCUIT DESCRIPTION
4.3.2 MIXER (U221), FIRST LO ANH‘LIFIER
(QBDl)
First mixer U221 mixes the receive frequency
with the ﬁrst injection frequency to produce the 52.95
MHz ﬁrst IF. Since high-side injection is used, the
injection frequency is 52.95 MHz above the receive
frequency. The RF signal is coupled to the mixer
through C21 1.
The first injection frequency from the VCO is
coupled to the ﬁrst local oscillator ampliﬁer Q301
through C301. L301 and C302 match 0301 to the
VCO. Bins for Q301 is provided by R301, R302 and
R303, and C303 decouples RF signals. Impedance
matching to the mixer is provided by L302, R304 and
C304.
4.3.3 AND’LIFIER (12222), CRYSTAL FILTER
(2121/2122), n= AMP (mm
The output of U221 is coupled to buffer Q222.
C222, R229 and Q222 match the 50 ohm output of
1.12.21. Bins for Q222 is provided by R228 and R229.
The output of Q222 is matched to crystal ﬁlter 2221
Via L222, C223 and R230. This ﬁlter presents a low
impedance to 52.95 MHz and attenuates the receive,
injection, and other frequencies outside the 5295
MHz passband.
2221 and 2222 form a 2—sectinn. 4-pole crysml
ﬁlter with a center ﬁequency of 52.95 MHz and a -3
dB passband 0” kHz (12.5 kHz BW) or 15 kHz (20/
25 kHz BW). This ﬁlter establishes the receiver selec—
tivity by attenuating the adjacent channel and other
signals close to the receive frequency. C232, C224,
and L223 adjust the coupling of the ﬁller. L224, C225
and C227 provide impedance matching between the
ﬁlter and 0221.
IF ampliﬁer 0221 ampliﬁes the 52.95 MHz IF
signal to recover ﬁlter losses and improves receiver
sensitivity. Biasing for QZZI is provided by R222,
R223, R225 and R225 and C228, C229 decouple RF
signals. The output of QZZI is coupled to the detector
by C230.
4.3.4 SECOND LO AMP/TRIPLER (0401), sec?
OND IF FILTER (Q901)
The input frequency to Q401 is 17.5 MHz from
TCXO Y801 coupled through C402. Bins for Q401 is
provided by R401, R402, R403 and R404. C403, ‘
C404 decouple RF from the ampliﬁer. L401, L402,
C405. C406 and C407 pass the third hennonic ofthe
input (52.5 MHz) to U24l, pin l. The output of the .
ampliﬁer is coupled to U24l, pin 1 by C241, and ‘
C410 and L404 provided low frequency decoupling.
4.3.5 SECOND MIXER/DETECTOR (U241)
Oscillator and Mixer
As shown in Figure 4-3, U241 contains the sec--
and oscillator, second mixer, limiter, detector, and
squelch circuitry. The 5295 MHz [F signal is mixed
with a 52.5 MHz signal produced by second L0
ampliﬁer Q401 from TCXO Y801.

Figure 4-3 U24l BLOCK DIAGRAM
Second IF Filter
The output ofthe internal double-balanced minor
is the difference between 52.95 MHz and 52.5 MHz
which is 450 kl-Lz. This 450 kHz signal is fed out on
pin 3 and applied to second IF ﬁlters Z241 and Z24L2.
These ﬁlters have passhands of 9 kHz (12.5 kHz BW),
15 kHz (20 kHz BW) or 20 kHz (25 kHz 13W) at the
-6 dB points and are used to attenuate widehand noise.
Limiter-Ampliﬁer
The output of 2241/2242 is applied to a limiter-
ampliﬁer 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 oﬂ" by
the limiter; however, when the 450 ld-lz signal level is
low, the noise passes through. C242, C243 decouple
the 450 kHz signal,
Quadrature Detector
From the limiter stage the signal is fed to the
quadrature detector. An external phase-shiﬁ network
mnneeted to pin 8 shiﬁs the phase of one of the detec-
tor inputs 90“ at 450 kHz (all other inputs are
unshiﬁed in phase), When modulation occurs, the fre-
quency of the [F 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 shift into an audio signal. L242 is tuned to
provide maximum undistorted output from the detec-
tor. R242 is used to lower the Q of L242. From the
detector the audio and data signal is fed out on pin 9.
Audio/Data Ampliﬁer
The audio/data output of [1241 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
R2611R262. R263 and R264 provide a 1.9V DC ref-
erence bias voltage. The audio output of U261 is
applied to 1201, pin 13.
Receive Si al Stren lndicator SSI
U24l, pin 13 is an output for the R551 circuit
which provides a current proportional to the strength
of the 450 kHz lF signal. The voltage developed
across R241 is applied to 1201, pin 12.
4.4 TRANSMITTER CIRCUTT DESCRIPTION
4.4.1 BUFFER (Q851)

ClRCUlT DESCRIPTION .
The low-pass ﬁlter consists of L561, C561, L562,
C562, L563, C563 and L564. The ﬁlter attenuates
spurious frequencies occurring 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, CRSGZ)
The antenna switching circuit switches the
antenna tn 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
through diode CRSGI. L566, diode CR562, and R562!
R563. When a diode is femard biased, it presents a
low impedance to the RF signal; conversely, when it is
reverse biased (or not conducting), il presens a high
impedance (small capacitance). Therefore, when
CR561 is forward biased, the transmit signal has a
low-impedance path to the antenna through coupling
capacitor C563.
C567, L566, and C570 hunt a discrete quarter-
wave line. When CR56l is forward biased, this quarv
ter-wave line is effectively AC grounded on me 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 antennatn
50 ohms in transmit and receive.
In the receive made, no power is applied to L565,
so all the dindes are "oﬁ". 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. ‘

5.1 GENERAL
5.1.1 PERIODIC CHECKS
This transceiver should be put on a regular main-
tenance schedule and an accurate performance record
maintained. Important checlm 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 drifting has occurred.
5. I .2 SURFACE-MOUNTED 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.
5.1.3 SCHEMATIC DIAGRAMS AND COMPO-
NENT LAYOUTS
Schematic diagrams and component layouts of
the PC boards used in this transceiver are located in
Section B. A component locator guide is also pm-
vidal to aid in componem location.
5.l .4 REPLACEMENT PARTS LIST
A replacement parts list with all the parts used in
this transceiver is located in Section 7, Parts are listed
alphanumerically according to designator. For infor-
mation on ordering parts, refer to Section 1.8,

5.2 SYNTHESIZER SERVICING
5.2.1 INTRODUCTION
When there is a synthesizer malfunction, the
VCO is not locked on frequency. When an unlock
VCO is detected by the lock detector circuit, [1801
pin 18 goes low (OV).
NOTE: The mer-ﬂpplied circuitry must disable ll
transmitter and receiver when an nul-oﬁlock cond
mm is indicated.
When the VCO is tmlocked, the fit and W in]:
to the phase detector are usually not in phase (see 1
tion 4.1.2). The phase detector in U801 then cans!
the VCO oonu-ol voltage to go to the high or low e
of its operating range. This in turn causes the VC(
oscillate at the high or low end of its ﬁeqwency m
As shown in Figure 4-1, a loop is formed by
VCO QSSO, ampliﬁer QXSl/QSSZ, and the RF I'N

loop. However, correct operation of the counters i
still be veriﬁed by measuring the input and output
quencies to check the divide number.
Proceed as follows to check the synthesizer I
signals to determine if it is operating properly.

The output level of QBS] can be measured v~
an RF voltmeter or some other type of high. impcd
meter. The minimum level after a power splitter.
R85] should be -10 dBm.
Check the DC voltage at C815 with a channel
near the center of the band. 11” the VCO is locked on
frequency, this should be a steady DC voltage near
3V. If it is not locked on frequency, it should be near
the lower or upper end of its range (OV or 5.5V).
W133!
Check the VCO frequency at R851. If the VCO
is locked on ﬁequency, it should be stable on the
transmit channel frequency. If the VCO is not leaked
on frequency, the VCO control voltage is probably
near UV or 5.5V.

Lock Detector
When the VCO is locked on frequency, the lock
deﬂect output on 1201, pin 7 should be high.
