Inputs include a 16.8 MHz clock from the synthesizer, recovered audio and squelch, MCU control signals, and external or internal microphones.

  • Page 24: Antenna Switch

    Theory of Operation 3.5.2 Antenna Switch The antenna switch circuit consists of two pin diodes (D3521 and D3551), a pi network (C3531, L3551, C3550), and two current limiting resistors (R3572-3). In the transmit mode, pin 32 of PCIC U3502 goes high which applies a B+ source to the antenna switch circuit to bias the diodes "on". The shunt diode (D3551) shorts out the receiver port and the pi network.

    Theory of Operation The IFIC is a low-voltage monolithic FM IF system incorporating a mixer/oscillator, two limiting IF amplifiers, quadrature detector, logarithmic received signal strength indicator (RSSI), voltage regulator and audio and RSSI op amps. The second LO frequency is determined by Y3200. Additional IF selectivity is provided by two ceramic filters, FL3204 (between the second mixer and IF amp) and FL3206 (between the IF amp and the limiter input).

  • Page 27: Fractional-N Synthesizer

    Theory of Operation 3.7.2 Fractional-N Synthesizer The Fractional-N synthesizer, shown in Figure 3-8, uses a 16.8 MHz reference oscillator (Y3762) to provide a high stability reference for the system. Stability is better than 2.5 ppm over temperatures of -30 to 60 °C. Electronic frequency adjustment is achieved by an internal DAC which provides a frequency adjustment voltage from U3701 pin 25 to the reference oscillator module.

It consists of a combination of lumped components (C102-7, L101-2) and microstrip elements. This type of filter has the advantage that it can give a greater attenuation in the stop-band for a given ripple level. The design was optimized to meet critical attenuation requirements for the second harmonic in the 1559- 1610 MHz GNSS band.
