    SRM9000X8 800MHz SERVICE MANUAL TECHNICAL DESCRIPTION ECEIVER Refer to Figure 3-1. Front End Filters and RF Amplifier 3.1.1 The receiver input signal from the antenna passes through the harmonic filter and antenna T/R switch. With the mobile in receive mode, diodes D580, D582 and D583 in the antenna switch are reverse biased allowing the receiver input signal to be coupled through to the receiver front-end with minimal loss.

The frequency synthesiser consists of the RX VCO, the second local oscillator VCO (90MHz), loop filters, varactor positive bias generator, reference oscillator, external divider and an integrated fractional N phase locked loop IC (U721).

  • Page 35: Reference Oscillators

    SRM9000X8 800MHz SERVICE MANUAL The divided reference signal is differentiated and discharges C778 via Q771, after which Q771 is turned off allowing C778 to recharge via constant current source Q772. The Schmitt Trigger comprising Q774, Q775 and Q776, converts the modulation combined with the sawtooth ramp, to a square wave output, the duty cycle of which is controlled by the ramp slope and modulation.
