GENERAL INFORMATION1-2Part No. 001-3422-0031.2.2 DL-3422 WITH LOADER BOARDThe DL-3422 includes the 8-channel Loader board (Part No. 023-3240-001), which performs synthesizer loading through an RS-232 DB-9 interface. In addition, this board has circuitry which provides electronic control of the following:Transmit/Receive data conditioning and gatingCarrier DetectPower ControlPreselector TrackingModulation FlatnessAudio/Data FilteringSleep/Wake-up to minimize current consumptionDiagnostics that includes: Input Voltage Sense Input Current Sense Ambient Temperature Sense RSSI Indicator (RSSI Sense) Forward/Reverse Power Sense. The gating circuits allow user selection of data filtering (standard or wide band) and also pre-emphasis/de-emphasis to be enabled or disabled.This board is programmed using an IBM PC or compatible computer and the Johnson Data Telemetry programming software. Programming information is stored by an EEPROM on the Loader board. Refer to Section 3 for programming information.NOTE: The synthesizer must be loaded each time power is turned on. Therefore, one loader board or customer supplied programming circuit is required for each data transceiver.1.2.3 DL-3422 WITH DL-3295 MODEMThe DL-3496 modem (Part No. 023-3295-001) provides digital data transmission at data rates up to 9600 baud. The DL-3295 operates in Half-Duplex mode. However, two transceivers can be combined to provide Full-Duplex operation. The user interface is a serial port through a 9-pin D-connector configurable to either RS-232 or TTL signal levels. The data format is asynchronous with either 8 or 9 data bits. The modem can operate in either standard DTE/DCE handshake p rotocol or in Data Activation mode which requires only receive and transmit data lines. The baud rates are user selectable from 300 to 9600 baud.1.2.4 DM-3422 SYNTHESIZER PROGRAMMINGThe DM-3422, when used without the Universal Loader Board (Part No. 023-3240-001) requires customer supplied circuitry to load the synthesizer with channel information. The protocol that this circuitry must follow is described in Section 3.

SECTION 22-1 Part No. 001-3422-003INSTALLATION1.1 PRE-INSTALLATION CHECKSField alignment should not be required before the 3422 is installed. However, it is still good practice to check the performance to ensure that no damage occurred during shipment. Performance tests are located in Section 6.2.1.1 INTERFACING WITH DATA EQUIPMENT1.1.1 DM-3422 (RF Board)Connector J201 on the data transceiver PC board provides the interface with the data equipment. This is a 14-pin female connector with .025" square pins on 0.1" centers (Dupont 76308-114). The cable (Part No. 023-3472-007) is not included with the data transceiver. An interface cable diagram and pin designations are shown in Figure 2-1.The following is a general description of the input and output signals on Transceiver Interface connector J201.Pin 1 (Ground) - Chassis ground.Pin 2 (+13.3V DC) - Input, transceiver main power. Input range 10-16V DC with ±3 dB variation in output power. Pin 3 (Tx En) - Input +3-16V DC. Enables transmit circuitry. ≤ 0.3V DC in Rx mode.Pin 4 (Rx En) - Input +3-16V DC. Enables receive circuitry. ≤ 0.3 V DC in Tx mode.Pin 5 (RF En) - Input +3-16V DC. Shuts down on-board regulators. To be used as a power save mode.Pin 6 (Mod In) - Provides a response of ±2 dB from DC to 5 kHz across the RF band (referenced to 1 kHz). It is programmable to 1 dB with the diagnostic DAC. The modulation capability is 250 mV RMS ±3 dB that produces ±5 kHz deviation with a 1 kHz tone. When this input is used, a temperature compensated 2.5V DC bias is required as variations in voltage cause the frequency to change.

SECTION 33-1 Part No. 001-3422-003PROGRAMMING3.1 INTRODUCTIONThe DL-3422 information in Section 3.2 describes synthesizer programming protocol. This information can be used as a basis for designing the synthesizer programming hardware and software.The DL-3422 VHF Transceiver uses a high performance Fractional-N Synthesizer and Voltage Controlled Oscillator (VCO). The Fractional-N Synthesizer offers high frequency resolution, fast lock times, and improved noise performance over conventional synthesis techniques. With conventional synthesizers, the phase detector comparison frequency must be equal to the channel spacing because the main divider can only change in integer steps. The channel spacing (resolution) of a Fractional-N synthesizer is a fraction of the comparison frequency. With the Fractional-N synthesizer, the comparison frequency is increased to 5 or 8 times the channel step frequency. The total loop division is reduced with a higher comparison frequency which improves phase noise. Lock times are improved because the loop bandwidth can be wider.3.2 DL-3422 SYNTHESIZER DATA PROTOCOL3.2.1 INTRODUCTIONProgramming the SA-7025 synthesizer IC (U811) is accomplished via the 3-line bus; DATA, CLOCK, and STROBE. Four 24 bit words (D, B, C, and A0) are required to load the synthesizer. The D, C, and B words contain four address bits each; the A0 word has a 1 bit address. Synthesizer frequency acquisition is initiated when the A0 word is loaded. We recommend using modulus 3 and sending the D, B, C, and A0 words for each synthesizer load (LONG load). When the STROBE = low, the clock driver is enabled and the DATA is clocked into the shift registers on the positive edges of the CLOCK. When STROBE = high, the clock is disabled and the data in the shift registers remain stable. The DATA is latched into different working (or temporary) registers depending on the address bit(s). In order to fully program the synthesizer, all four words must be sent with the A0 word sent last. Refer to Table 3-1 and Figure 3-3 for data format information.3.2.2 PROGRAMMING SYNTHESIZER PARAMETERSThe DL-3422- RF Board is available in three frequency ranges, 132-150 MHz (Band 4), 150-174 MHz (Band 5), and 150-174 MHz (Band 6). Band 6 was designed to be compatible with the FCC’s refarmed VHF band plan therefore, 2.5 kHz channel resolution is used. The Band 4 and 5 versions can be programmed for 5, 6.25, and 7.5 kHz steps depending on user requirements.

The LOCK output is high when the main and auxiliary phase detectors indicate a lock condition. The lock condition is defined as less then +1 cycle on the reference input to the synthesizer IC.

Then, the SYNTH_EN is returned to a low state.4. After the A0 Word is strobed in, wait 7ms (worst case) before applying a logic high to the 7.5 TX 1 line (J201, pin 3). This allows the synthesizer to attain lock. NOTE: The lock detect line (J201, pin 7) should be monitored and in a lock (logic high) state before enabling the transmitter.1 A "ramp-up/-down" circuit should be employed on the Loader to minimize adjacent channel interference caused by the spectral spreading that occurs when a transmitter is suddenly switched on or off.

SECTION 44-1 Part No. 001-3422-003CIRCUIT DESCRIPTION4.1 GENERAL4.1.1 INTRODUCTIONThe main subassemblies of this transceiver are the RF board, VCO board, TCXO and Loader board. A block diagram of the transceiver is located in Figure 4-1. The 3422 is available with a reference oscillator stability of ±2.5 PPM. The TCXO (Temperature Compensated Crystal Oscillator) is soldered directly to the RF board. The TCXO is not serviceable.4.1.2 SYNTHESIZERThe 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 21.45 MHz above the receive frequency. The frequency of this oscillator is controlled by a DC voltage produced by the phase detector in synthesizer chip U811.Channels are selected by programming counters in U811 to divide by a certain number. This programming is performed over a serial bus formed by the Synth Clock, Synth Enable, and Synth Data pins of J201. This programming is performed by the Loader board or user supplied hardware and software (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 +140° F).Table 4-1 Reference FrequencyBand FrequencyBand 6 17.5 MHzBand 5 14.85 MHzBand 4 14.85 MHz
CIRCUIT DESCRIPTION4-2Part No. 001-3422-0034.1.3 RECEIVERThe receiver is a double-conversion type with intermediate frequencies of 21.45 MHz / 450 kHz. Varactor tuned LC bandpass filters reject the image, half IF, injection, and other unwanted frequencies. A four-pole crystal filter enhances receiver selectivity.4.1.4 TRANSMITTERThe transmitter produces a nominal RF power output of 5W at 13.3V DC, adjustable down to 1W. Frequency modulation of the transmit signal occurs in the synthesizer. Transmit audio processing circuitry is contained in the Loader board or customer-supplied equipment.4.1.5 LOADER BOARDThe Loader board, Part No. 023-3240-330, is a plug-in circuit board used to load the synthesizer with a desired frequency and filters data/audio to and from the user interface connector. The Loader board is programmed by a personal computer and software.4.2 SYNTHESIZERA block diagram of the transceiver is shown in Figure 4-1 and a block diagram of Synthesizer IC U811 is shown in Figure 4-2. The synthesizer output signal (produced by a VCO) is controlled by a DC voltage produced by the phase detector in U811. 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 frequency.Synthesizer programming provides the data necessary for the internal prescaler and counters. One input signal is the reference frequency. This frequency is produced by the 14.85 MHz reference oscillator (TCXO). The other input signal is the VCO frequency.

CIRCUIT DESCRIPTION4-5 Part No. 001-3422-003Frequency Control and ModulationThe VCO frequency is controlled in part by DC voltage across varactor diodes CR852, CR853 and CR854. As voltage across a reverse-biased varactor diode increases, its capacitance decreases. Therefore, VCO frequency increases as the control voltage increases. CR852/CR853 and CR854 are paralleled varactors to divide the capacitance and improve linearity. The varactors CR852/CR853 are biased at -2.0V so the control line voltage can operate closer to ground. CR854 is pin shifted in when transmitting to increase the VCO gain in transmit. The control line is isolated from tank circuit RF by choke L852/L853. The amount of frequency change produced by CR852/CR853/CR854 is controlled by series capacitor C854.The -2.0V applied to the VCO is derived from the TCXO frequency that is amplified by Q902, rectified by CR902 and filtered by C912, C917, C918 and C920 and loaded by resistor R919 on the RF board.The VCO frequency is modulated using a similar method. The transmit audio/data signal from J201, pin 6 is applied across varactor diode CR861 which varies the VCO frequency at an audio rate. Series capacitors C855/C856 set the amount of deviation produced along with CR862 and C865. R863 provides a DC ground on the anodes of CR861/CR862, and isolation is provided by R862 and C863.The DC voltage across CR862 provides compensation 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 CR852/CR853/CR855 gets lower). CR862 also balances the modulation signals applied to the VCO and TCXO. The D/A Converter U911 can be programmed to apply a compensating voltage to CR862 to adjust the modulation sensitivity between the TCXO and VCO.The DC voltage applied across CR862 comes from the modulation adjust control R827 on the RF board. R826 applies a DC biasing voltage to CR862; C821 provides DC blocking. RF isolation is provided by C865 and R862.4.2.2 VCO AND REFERENCE OSCILLATOR MODULATIONBoth the VCO and reference oscillator (TCXO) are modulated in order to achieve the required frequency response. If only the VCO was modulated, the phase detector in U811 would sense the frequency change and increase or decrease the VCO control voltage 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. Potentiometers R825 and R827 set the VCO modulation sensitivity so that it is equal to the reference oscillator modulation sensitivity.
CIRCUIT DESCRIPTION4-6Part No. 001-3422-0034.2.3 CASCODE AMPLIFIERS/VCO (Q871/Q872)The output signal on the collector of Q871 is coupled to buffer amplifier Q872 which forms a cascade amplifier. This is a shared-bias amplifier which provides amplification and also isolation from the stages that follow. The signal is coupled and matched from the collector of Q872 through inductors and capacitors and a T-pad to amplifier Q882.4.2.4 AMPLIFIER (Q882)Amplifier Q882 provides final amplification of the VCO signal. Bias for Q882 is provided by Q881 and several resistors. Matching to the transmitter and receive first injection is provided by L891 and C892. A 6 dB T-pad is used to isolate the transmitter and receive first injection.4.2.5 VOLTAGE FILTER (Q901)Q901 on the RF board is a capacitance multiplier to provide filtering of the 8.6V supply to the VCO. R901 provides transistor bias and C901 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 C901. Therefore, base current does not change and transistor current remains constant. CR901 decreases the charge time of C901 when power is turned on. This shortens the start-up time of the VCO. C902 and C903 are RF decoupling capacitors.4.2.6 VCO FREQUENCY SHIFT (Q841)The VCO must be capable of producing frequencies from approximately 132-195.45 MHz to produce the required receive injection and transmit frequencies. 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 shift (RX_EN) on J201, pin 4, Q841/Q842 and pin diode CR851. When a pin diode is forward biased, it presents a very 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 J201, pin 4 is high in receive (+5V), Q173 is turned on and the collector voltage goes low. A low on the base of Q172 turns the transistor on and the regulated +9.6V on the emitter is on the collector for the receive circuitry. Q171 applies a low on the base of Q841, the transistor is off and the collector is high. With a high on the base of Q842 and a low on the emitter, this reverse biases CR851 for a high impedance.The capacitive leg on the VCO board is formed by C852, CR851 and C853. When J201, pin 4 is low in transmit, Q842 is turned on and a high is on the emitter, Q171 is turned off and the collector voltage goes high. A low on the base of Q173 turns the transistor off and the regulated +9.6V is removed from the receive circuitry. With a high on the base of Q841 the transistor is on and the collector is low. With a low on the collector of Q842 and a high on the emitter, this forward biases CR851 and provides an RF ground through C852 and C853 is effectively connected to the tank circuit. This decreases the resonant frequency of the tank circuit.
CIRCUIT DESCRIPTION4-7 Part No. 001-3422-0034.2.7 SYNTHESIZER INTEGRATED CIRCUIT (U811)IntroductionSynthesizer chip U811 is shown in Figure 4-2. This device contains the following circuits: R (reference), Fractional-N, NM1, NM2 and NM3; phase and lock detectors, prescaler and counter programming circuitry. The basic operation was described in Section 4.2.1.Channel ProgrammingFrequencies are selected by programming the R, Fractional-N, NM1, NM2 and NM3 in U811 to divide by a certain number. These counters are programmed by Loader board or a user supplied programming circuit. More information on programming is located in Section 3.As previously stated, the counter divide numbers are chosen so that when the VCO is oscillating on the correct frequency, the VCO-derived input to the phase detector is the same frequency as the reference oscillator-derived frequency.The VCO frequency is divided by the internal prescaler and the main divider to produce the input to the phase detector.4.2.8 LOCK DETECTWhen the synthesizer is locked on frequency, the SYNTH LOCK output of U811, pin 18 (J201, pin 7) is a high voltage. When the synthesizer is unlocked, the output is a low voltage. Lock is defined as a phase difference of less than 1 cycle of the TCXO.4.3 RECEIVER CIRCUIT DESCRIPTION4.3.1 PRESELECTOR FILTER, RF AMPLIFIER (Q202)Capacitor C201 couples the receive signal from the antenna switch to the LC preselector filter composed of L201-L203, CR281, CR282, C202-C207. (The antenna switch is described in Section 4.4.4.) The preselector filter is a 2-pole discrete LC varactor tuned bandpass filter adjusted to pass only a narrow band of frequencies to the receiver. This attenuates the image and other unwanted spurious frequencies. The preselector filter is tuned in frequency by varying the reverse bias voltage of varactors CR281/CR282. The filter control voltage is either generated by Digital to Analog Converter (DAC) U911 or R920 and amplified by U831 to generate a higher voltage swing to the varactors and minimize filter loss. R206 and capacitors C281-C285 filter the varactor voltage and provide RF isolation. The control voltage source is chosen by U913.Impedance matching between the helical filter and RF amplifier Q202 is provided by C207 and L204. CR201 protects the base-emitter junction of Q202 from excessive negative voltages that may occur during high signal conditions. Q201 is a switched constant current source which provides a base bias for Q202. Q201 base bias is provided by R202/R203. Current flows through R201 so that the voltage across it equals the voltage across R202 (minus the base-emitter drop of Q201). In the transmit mode the receive +9.6V is removed and Q201 is off.
CIRCUIT DESCRIPTION4-8Part No. 001-3422-003 This removes the bias from Q202 and disables the RF amplifier in transmit mode. This prevents noise and RF from being amplified by Q202 and fed back on the first injection line.Additional filtering of the receive signal is provided by a three pole discrete LC varactor tuned bandpass filter composed of filter L212-L214, L221-L224, CR283-CR285, C214-C217, C221-C223. L211 and C213 provide impedance matching between Q202 and this filter. Resistor R205 is used to lower the Q of L211 to make it less frequency selective. The same control voltage that adjusts to two pole filter on frequency adjusts this filter as well. The inductors are factory tuned to align the filter tracking and should not be adjusted.4.3.2 MIXER (U231), AMPLIFIER (Q231)First mixer U231 mixes the receive frequency with the first injection frequency to produce the 21.45 MHz first IF. Since high-side injection is used, the injection frequency is 21.45 MHz above the receive frequency. The RF signal is coupled to the mixer through C232.The output of U231 is coupled to buffer Q231. C232, R233 and Q231 match the 50 ohm output of U231. The output of Q231 is matched to crystal filter Z231 via L231 and C234. This filter presents a low impedance to 21.45 MHz and attenuates the receive, injection, and other frequencies outside the 21.45 MHz passband.4.3.3 FIRST LO AMPLIFIER/BUFFER (Q301, Q302)The first LO amplifier provides amplification and buffering of the receive first injection. R305-R307 form a 3 dB 50 ohm pad. C303 couples the signal to C304 and L301 which match Q302 to 50 ohms. L302 and C307 match Q302 to the mixer Q232. Q301, R301-R304 provide biasing for Q302. R308 enhances the stability of Q302. C302 and C306 provide RF decoupling.4.3.4 CRYSTAL FILTER (Z231/Z232)The output of Q231 is matched to the crystal filter, Z231/Z232 by L231, C234 and C237. This filter presents a low impedance to 21.45 MHz and attenuates the receive, injection and other frequencies outside the 21.45 MHz passband. Z221 and Z222 form a 2-section, 4-pole crystal filter with a center frequency of 21.45 MHz and a -3 dB passband of 8 kHz (15 kHz BW) or 15 kHz (30 kHz BW). This filter establishes the receiver selectivity by attenuating the adjacent channel and other signals close to the receive frequency. C241, and C242 adjust the coupling of the filter. L242, C244, C245 and R243 provide impedance matching between the filter and U241.
CIRCUIT DESCRIPTION4-9 Part No. 001-3422-003Figure 4-3 U241 Block Diagram4.3.5 FM IF (U241)Second LO Oscillator, Buffer (Q251)As shown in Figure 4-3, U241 contains the second oscillator, second mixer, limiter, detector, and squelch circuitry. The second LO oscillator is built into U241 which provides the base and emitter connections for an internal oscillator transistor. The oscillator tank circuit consists of L251, C253 and CR251. Oscillator feedback is provided by C254, C256 and C257. The oscillator frequency is adjusted by applying a control voltage across R253 to CR251. The control voltage is provided by the charge pump of the auxiliary synthesizer in U811. The emitter of the oscillator transistor is connected to the common collector buffer amplifier Q251 by C251. R257-R259 and R254 provide bias for Q251. R254 additionally provides an RF load to decrease the buffer level. C258, C259 and L252 filter the unwanted harmonics from the oscillator output. The output of Q251 is coupled to the auxiliary synthesizer phase detector by C814. The oscillator is phase locked at 21.9 MHz with L251 adjusted to center the control voltage.Second IF FilterThe output of the internal double-balanced mixer is the difference between 21.45 MHz and 21.9 MHz which is 450 kHz. This 450 kHz signal is fed out on pin 3 and applied to second IF filters Z241 and Z242. These filters have passbands of 9 kHz (15 kHz BW), or 20 kHz (30 kHz BW) at the -6 dB points and are used to attenuate wideband noise.124MIXER5151411RSSI52.95 MHzC234C26720OSCILLATOR52.5 MHz+-RSSI OUTPUT9VREG6VCC78+-10 QUADAUDIO OUTPUTL25312133NCLIMITER INLIMITERIF AMP OUTIF DEC1IF DEC2IF AMP INMIXER OUTLIMITER DEC1LIMITER DEC2LIMITER OUTIF AMP16171819RSSI FBAUDIO FB
CIRCUIT DESCRIPTION4-10Part No. 001-3422-003Limiter-AmplifierThe output of Z241/Z242 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 off by the limiter; however, when the 450 kHz signal level is low, the noise passes through the limiter. C275/C276 decouple the 450 kHz signal.Quadrature DetectorFrom the limiter stage the signal is fed to the quadrature detector. An external phase-shift network connected to pin 8 shifts the phase of one of the detector inputs 90° at 450 kHz (all other inputs are unshifted in phase). When modulation occurs, the frequency of the IF signal changes at an audio rate as does the phase of the shifted input. The detector, which has no output with a 90° phase shift, converts this phase shift into an audio signal. L253 is tuned to provide maximum undistorted output from the detector. R255 is used to lower the Q of L253. From the detector the audio and data signal is fed out on pin 9. The audio/data output of U241, pin 9 is applied to J201, pin 13.Receive Signal Strength Indicator (RSSI)U241, pin 5 is an output for the RSSI circuit which provides a current proportional to the strength of the 450 kHz IF signal. The voltage developed across R275 is applied to J201, pin 12.4.4 TRANSMITTER CIRCUIT DESCRIPTION4.4.1 BUFFER (Q501)The VCO RF output signal is applied to R892, R893 and R894 that form a resistive splitter for the receive first local oscillator and the transmitter. The VCO signal is then applied to a 50 ohm pad formed by R501, R502, and R503. This pad provides attenuation and isolation. Q501 provides amplification and additional isolation between the VCO and transmitter. Biasing for this stage is provided by R504 and R505, and decoupling of RF signals is provided by C503 . Impedance matching to the predriver is provided by L511 and C512.4.4.2 PRE-DRIVER (Q511)Pre-driver Q511 is biased Class A by R511 and R512 and R515. L513, C517 and C518 match Q511 to U531. R514 provides a resistive feedback path to stabilize Q511 and C515 provides DC blocking. C516 bypasses RF from the DC line, and R513 provides supply voltage isolation and ties the +9V transmit supply to the circuit.
CIRCUIT DESCRIPTION4-11 Part No. 001-3422-0034.4.3 FINAL (U531), COMPARATOR (U111C)RF module U531 has an RF output of 1W to 5W and operates on an input voltage from 10-16V.Power control is provided by U581, U111, Q531 and a directional coupler A531. The power is adjusted by Power Set Control R535 that provides a reference voltage to U111C. U111C drives Q531 and PA module U531. One end of the Balun directional coupler is connected to a forward RF peak detector formed by R591, CR591, C591 and U581A. The other end of the directional coupler is connected to a reverse RF peak detector formed by R593, CR592, C593 and U581B. If the power output of U531 decreases due to temperature variations, etc., the forward peak detector voltage drops. This detector voltage drop is buffered by U581A and applied to inverting amplifier U111C which increases the forward bias on Q531. The increase on Q531 increases the power output level of U531. If the power output of U531 increases, the forward peak detector voltage increases and U111C decreases the forward bias on Q531. The decrease on Q531 decreases the output power of U531.The output of CR591/CR592 is fed to U581A/B respectively. If the output of either buffer increases, the increase is applied to the inverting input of U111C. The output of U111C then decreases and Q531 decreases the input voltage to U531 to lower the power. The control voltage is isolated from RF by ferrite bead EP532 and C531 decouples RF.The forward/reverse power voltages from U581A/B are also applied to U913/U912 for outputs on J201.The low-pass filter consists of L551-L554, and C552-C556. The filter attenuates spurious frequencies occurring above the transmit frequency band. The transmit signal is then fed through the antenna switch to antenna jack J501.4.4.4 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, +9V is applied to L555 and current flows through diode CR561, L561, diode CR562, and R561. When a diode is forward biased, it presents a low impedance to the RF signal; conversely, when it is reverse biased (or not conducting), it presents 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 C562.L561 and C563 form a discrete quarter-wave line. When CR561 is forward biased, this quarter-wave line is effectively AC grounded on one end by C563. 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. C561/C563 match the antenna to 50 ohms in transmit and receive.
CIRCUIT DESCRIPTION4-12Part No. 001-3422-0034.4.5 TRANSMITTER KEY-UP CONTROLQ121, Q122 and Q123 act as switches which turn on with the RX_EN line. When the line goes low Q121 is turned off, which turns Q122 on, turning Q123 on. This applies 13.6V to U111 before the TX_EN line goes high.U111A/B provide the key-up and key-down conditioning circuit. C116 and R117 provide a ramp-up and ramp-down of the 9V transmit supply during key-up and key-down which reduces load pull of the VCO during key-up. The conditioning provides a stable 5.5V output by balancing the 5.5V reference with the 5.5V regulated supply. The output on U111B, pin 7 is applied to comparator U111D, pin 12, the non-inverting input. The output of U111D, pin 14 is applied to the b ase of current source Q124. The output of Q124 is on the emitter and is applied back to the inverting input of comparator U111D, pin 13. A decrease or increase on U111D, pin 13 causes a correction by U111D to stabilize the 9V transmit output. R125/R126 establish the reference voltage on U111D, pin 13. C123 provides RF bypass, C124 provides RF decoupling and C125 stabilizes the output. The 9V transmit voltage is then distributed to the circuits.4.5 VOLTAGE REGULATORS4.5.1 +9.6 AND +5.5V REGULATEDThe +5V applied on J201, pin 5 is applied to the base of Q131 turning the transistor on. This causes the collector to go low and applies a low to the control line of U141, pin 1 and R131 is a pull-up resistor. The 13.6V from J201, pin 2 is on U141, pin 6 to produce a +9.6V reference output on U141, pin 4. C145 stabilizes the voltage and C146 provides RF decoupling. C144 provides RF bypass and C118 provides RF decoupling. C137 is a bypass capacitor for U131.The low from the collector of Q131 is also applied to the control line of U131, pin 1. C136 decouples RF and R131 is a pull-up resistor. The 13.6V from J201, pin 2 is on U131, pin 6 to produce a +5.5V output on U131, pin 4. C135 stabilizes the voltage and C136 provides RF decoupling. C137 is a bypass capacitor for U131.
SECTION 55-1Part No. 001-3422-003SERVICING5.1 GENERAL5.1.1 PERIODIC CHECKSThis transceiver should be put on a regular maintenance schedule and an accurate performance record maintained. Important checks are receiver sensitivity and transmitter frequency, modulation, and power output. A procedure for these and other tests is located in Section . It is recommended that transceiver performance 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.5.1.2 SURFACE-MOUNTED COMPONENTSA 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 component 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 COMPONENT LAYOUTSSchematic diagrams and component layouts of the PC boards used in this transceiver are located in Section . A component locator guide is also provided to aid in component location.5.1.4 REPLACEMENT PARTS LISTA replacement parts list with all the parts used in this transceiver is located in Section . Parts are listed alphanumerically according to designator. For information on ordering parts, refer to Section 1.8.5.1.5 TCXO MODULE NOT SERVICEABLEThe ±2.5 PPM TCXO module is not field serviceable. Part changes require a factory recalibration to ensure that the oscillator stays within its ±2.5 PPM tolerance.5.2 SYNTHESIZER SERVICING5.2.1 INTRODUCTIONWhen there is a synthesizer malfunction, the VCO is not locked on frequency. When an unlocked VCO is detected by the lock detector circuit, U811, pin 18 goes low (0V). NOTE: The user-supplied circuitry must disable the transmitter and receiver when an out-of-lock condition is indicated.
SERVICING5-2Part No. 001-3422-003When the VCO is unlocked, the fR and fV inputs to the phase detector are usually not in phase (see Section 4.1.2). The phase detector in U811 then causes the VCO control voltage to go to the high or low end of its operating range. This in turn causes the VCO to oscillate at the high or low end of its frequency range.As shown in Figure 4-1, a loop is formed by VCO Q872, amplifier Q871, and the RF IN of U811. Therefore, if any of these components begin to malfunction, improper signals appear throughout the loop. However, correct operation of the counters can still be verified by measuring the input and output frequencies to check the divide number.Proceed as follows to check the synthesizer I/O signals to determine if it is operating properly.5.2.2 REFERENCE OSCILLATORCheck the signal at U811, pin 8. It should be 14.85 MHz for Bands 4 and 5 or 17.5 MHz for Band 6 at a level of approximately 0.5V P-P. If the TCXO module is defective, it is not serviceable and must be replaced with a new module as described in Section 5.1.5.5.2.3 VCOOutput Level The output level of Q882 can be measured with an RF voltmeter or some other type of high impedance meter. The minimum level after a power splitter at R851 should be -3 dBm.Control VoltageCheck the DC voltage at C815 with a channel near the center of the band. If 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 (0V or 5.5V).Output FrequencyCheck the VCO frequency at R851. If the VCO is locked on frequency, it should be stable on the transmit channel frequency. If the VCO is not locked on frequency, the VCO control voltage is probably near 0V or 5.5V.5.2.4 SYNTHESIZER (U811)Lock DetectorWhen the VCO is locked on frequency, the lock detect output on J201, pin 7 should be high.
