CIRCUIT DESCRIPTION TRANSMITTER The transmitter is comprised of: • Audio amplifier connections from J902 pin 1 • Frequency Synthesizer • Transmitter • Automatic Power Control Audio frequency connections and applied to the TCXO VC Frequency synthesizer circuit • 12.8 MHZ Tcxo • Voltage Controlled Oscillator (VCO) module • • • Dual Modulus Prescaler PAGE4 PLL Synthesizer The PLL synthesizer circuit is common to both the transmitter and receiver, The synthesizer comprises: Data RF Out 12.8 MHZ TCXO X1 is VCTCXO , which provide stable oscillator of 12.8 MHZ to PLL IC. Frequency adjustment is provided by VR1 .Voltage controlled oscillator module(VCO) The module produces carrier frequencies during transmit and local oscillator frequencies During receive. TCXO 8V Regulator Charge Pump Loop Filter IC1 PLL TX OR RX VCO VCO Dual modulus prescaler The prescaler divides the VCO frequency by 64 or 65. Transmitter The transmitter comprises: VCO Buffer PA Module Amp PAGE7 RF LPF ANTENNA SWITCH Automatic Power Control Buffer When the radio is in transmit mode the diode D201 is forward biases enabling the modulated RF signal from the VCO to pass to the buffer/pre-amplifier Q204 and associated components. The output signal is passed from Q204 to Q205 via a matching network consisting of Inductor L201 and C208. PA module The signal is then amplified for transmission by 207, which is a power amplifier module. Low pass filter The amplified RF signal is passed through the stripline coupler and is fed to the harmonic low pass filter, comprising L213 to L214 and C232-C234 and then to the antenna connector (ANT). Antenna Switch When transmitting, the diodes D205 are forward biased, allowing the RF to pass to the antenna. D205 is shorted to ground which makes L212 look open circuit (1/4 wave tuned stub). This prevents the TX signal from passing to the receiver stage. Power output control . The RF power tuning by VC2,which make sure the current less than 1300mA@5W output power. PAGE8 Receiver The receiver comprises: SAW FILTER& Amp IF Amp Data Out PAGE9 Rx VCO ANTENNA SWITCH First Mixer IF Filter Second Mixer Local Oscillator FM Limiter- Discnminator Squelch Circuit IF Filter Audio Filter Antenna Switch In receive, the diode D205 are reverse biased. L212 is now in circuit, passing the signal from the antenna to the SAW filter of F101. SAW FILTER The receiver signal is routed to pin 4 of the F101. It passes through the band pass filter . The input signal is coupled to the base of Q101 which serves as an RF amplifier. The output of Q101 is then coupled to the first mixer. First Mixer Q102, 2-pole crystal filters XF1 and coils L103 and C120 form the First Mixer and First IF Filter. The RF signal, from the SAW filter and amplifier Q101 is applied…
