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.

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.

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 MODE and slightly improves lock times. 4. Afier the last word is seabed in, 7 milliseconds (worst case) should elapse before 7.5 TX is turned ON.

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.

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 applied through R81 1. RF isolation is provided by 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. '_' '_'[»Jl-TOE:WEI "I'NFEHNHI'ILINHL lNL NU. Q 12 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. 4.2.6 VOLTAGE FILTER (Q832) Q832 is a capacitance multipliertoprovide filo-rs. ,. 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 and the collector is low.

This decreases the resonant frequency of the tank circuit. 4.2.3 swrnssrzaa INTEGRATED cmcmr (usm ) Introduction Synthesizer chip U801 is shown in Figure 4-2.

(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 RF amplifier QZOI is provided by C203, C21 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 and R203; and C208/C209 provide RF bypass. C protects the basecmitterjunction of QZOH from < sive negative voltages that may occur during hig nal conditions. Additional filtering ofthle receiv nal is provided by 2202.

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. net-cumin 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) The output signal is applied to a 50-ohm pad formed by R851, R852, and R853.

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. ‘ I’TI/Z’T/ 1 11:32 wQUENET INTERNHTIDNHL INC SECTION 5 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.

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.

NOTE: The mer-flpplied circuitry must disable ll transmitter and receiver when an nul-ofilock cond mm is indicated.

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. 5.2.5 SYNTHESIZER (U801) Lock Detector When the VCO is locked on frequency, the lock deflect output on 1201, pin 7 should be high. 5.3 RECEIVER SERVICING To isolate a receiver problem to a specific sec- tion, refer to the troubleshooting flowchart in Figure 5-1.
