61. 4 1 2 Antenna Switch The antenna switch circuit consists of two PIN diodes CR101 and CR102 a pi network C107 L104 and C106 and two current limiting resistors R101 R170 In the transmit mode B at PCIC U102 pin 23 will go low and turn on Q111 where a B bias is applied to the antenna switch circuit to bias the diodes on The shunt diode CR102 shorts out the receiver port and the pi network which operates as a quarter wave transmission line transforms the low impedance of the shunt diode to a high impedance at the input of the harmonic filter In the receive mode the diodes are both off and hence there exists a low attenuation path between the antenna and receiver ports Harmonic Filter The harmonic filter consists of C104 L102 C103 L101 and C102 The design of the narmonic filter for VHF is that of a modified Zolotarev design It has been optimized for efficiencv oi the power module This type of filter has the advantage that it can give a greater attenuaticn in tie stop band for a given ripple level The harmonic filter insertion loss is typically less thaz 1 288 Antenna Matching Network A matching network which is made up of L116 is used to match the 5 impedance to the harmonic filter This will optimize the performance of the transmitter and receiver into an antenna Power Control Integrated Circuit PCIC The transmitter uses the Power Control IC PCIC 0102 to regulate the power output of the radi

C232 C233 R231 R232 and R233 provides the necessary dc steering voltage for the VCO and determines the amount of noise and spur passing through In achieving fast locking for the synthesizer an internal adapt charge pump provides higher current at pin 45 of U201 to put synthesizer within the lock range The required frequency is then iockec by normal mode charge pump at pin 43 Both the normal and adapt charge pumps get their supply from the capacitive voltage multiplier which is made up of C258 C259 C228 triple diode CR201 and level shifters U210 U211 Two 3 3V square waves 180 deg out of phase are first shifted to 5V then along with requiated 5V put through arrays of diodes and capacitors to build up 13 3V at pin 47 cf U201 LOCK i 0409 PIN 56 DATA FREFOUT 0201 PIN 21 amp U404 PIN 34 CLK GND CEX U251 CSX U409 PIN 2 STEERING LOW VOLTAGE LINE MOD IN 0404 PIN 40 MODIN FRACTIONAL N 2 POLE 13 30 SYNTHESIZER ADAPT LOOP 5V U247 PIN 4 cc FILTER U248 PIN 5 Vpn 3 3V MODOUT Y S LO RF INJECTION REFERENCE AUXA UAL OSCILLATOR TRANSIS XTAL2 AUX3 TORS WARP VOLTAGE sFoUT 28 FILTERED 5V CONTROLLED PRENN gt OSCILLATOR BIASI ver eee 2 VMULTI Aux BIAS2 TX RF INJECTION VOLTAGE LLL 1ST STAGE OF PA MULTIPLIER
73. C304 CR301 and CR302 The bandpass filter is tuned by a control voltage to the varactor diodes CR301 and CR302 in the filter The bandnass filter is electronically tuned by the DACRx from IC404 which is controlled by the microprocessor Depending on the carrier frequency the DACRx will supply the tuned voltage to the varactor diodes in the filter Wideband operation of the filter is achieved by shifting the bandpass filter across the band The output of the bandpass filter is coupled to the RF amplifier transistor Q301 via C307 After being amplified by the RF amplifier the RF signal is further filtered by a second varactor tuned bandpass filter consisting of L306 L307 C313 C317 CR304 and CR305 Both the pre and post RF amplifier varactor tuned filters have similar responses The 3 dB bandwidth of the filter is about 50 MHz This enables the filters to be electronically controlled by using a single control voltage which is DACRx Receiver 5B 7 5 2 The output of the post RF amplifier filter which is connected to the passive double balanced mixer consists of T301 T302 and CR306 Matching of the filter to the mixer is provided by C381 After mixing with the first LO signal from the voltage controlled oscillator VCO using low side injection the RF signal is down converted to the 45 1 MHz IF signal The IF signal coming out of the mixer is transfered to the crystal filter FL301 through a resistor pad and a diplexer

110. 1 This IF IC is electronicativ crogrammable and the amount of filtering which is dependent on the radio channel spacing is controlled by the microprocessor Additional filtering once externally provided by the conventional ceramic filters is replaced by internal filters in the IF module U301 The IF IC uses a type of direct conversion process whe eby ihe externally generated second LO frequency is divided by two in U301 so that it is very close to the first IF frequency The IF IC U301 synthesizes the second LO and phase locks the VCO to irack the first IF frequency The second LO is designed to oscillate at twice the first IF frequency because of the divide by two function in the IF IC In the absence of an IF signal the VCO will searcii for a frequency or its frequency will vary close to twice the IF frequency When an IF signal is received the VCO will lock onto the IF signal The second LO VCO is a Colpitts oscillator around transistor 0320 The VCO has varactor diode CR310 to adjust the VCO frequency The control signal for the varactor is derived from a loop filter consisting of C362 C363 C364 Fi320 and R321 The IF IC 0301 also performs several other functions It provides a received signal strength indicator RSSI and a sque ch output The RSSI is dc voltage monitored by the microprocessor and used as a peak indicator auring the bench tuning of the receiver front end varactor filter The RSSI voltage is also u

C322 and L310 Matching to the input of the crystal filter is provided by C324 and L311 The crystal filter provides the necessary selectivity and intermodulation protection Receiver Back End Refer to UHF Receiver Back End Schematic Diagram on page 5B 22 The output of crystal filter FL301 is matched to the input of IF amplifier transistor Q302 by components R352 and C325 Voltage supply to the IF amplifier is taken from the receive 5 volts R5 The IF amplifer provides a gain of about 7dB The amplified IF signal is then counted into U301 pin 3 via C330 C338 and L330 which provides the matching for the IF amplifier and U301 The IF signal applied to pin of is amplified down converted filtered and demodulated to produce the recovered audio at pin 27 of U301 This IF IC is electronicativ crogrammable and the amount of filtering which is dependent on the radio channel spacing is controlled by the microprocessor Additional filtering once externally provided by the conventional ceramic filters is replaced by internal filters in the IF module U301 The IF IC uses a type of direct conversion process whe eby ihe externally generated second LO frequency is divided by two in U301 so that it is very close to the first IF frequency The IF IC U301 synthesizes the second LO and phase locks the VCO to irack the first IF frequency The second LO is designed to oscillate at twice the first IF frequency because of the divide by two func

173. Schematic Diagram 50 22 and 330 400MHz Transmitter Schematic Diagram on page 5D 26 The RF signal is received by the antenna and applied to a low pass filter For VHF the filter consists of L101 L102 C102 C103 C104 The filtered RF signal is passed through the antenna switch The antenna switch circuit consists of two PIN diodes CR101 and CR102 and a pi network C106 L104 and C107 The signal is then applied to a varactor tuned bandpass filter The VHF bandpass filter comprises o t391 1 302 C302 C303 C304 CR301 and CR302 The bandpass filter is tuned by a control voltage to the varactor diodes CR301 and CR302 in the filter The bandnass filter is electronically tuned by the DACRx from 0404 which is controlled by the microprocessor Depending on the carrier frequency the DACRx will supply the tuned voltage to the varactor diodes in the filter Wideband operation of the filter is achieved by shifting the bandpass filter across the band The output of the bandpass filter is coupled to the RF amplifier transistor Q301 via C307 After being amplified by the RF amplifier the RF signal is further filtered by a second varactor tuned bandpass filter consisting of L306 L307 C313 C317 CR304 and CR305 Both the pre and post RF amplifier varactor tuned filters have similar responses The 3 dB bandwidth of the filter is about 50 MHz This enables the filters to be electronically controlled by using a single control
