450KHz. The first local oscillator signal is supplied by PLL circuit. The PLL circuit in the transmitter generates the necessary frequencies. Fig.1 shows the frequencies. RPV516 frequency range: RPV516 A: 150MHz—174MHz RPU416 frequency range: RPU416 B: 400MHz—420MHz RPU416 A: 450MHz—470MHz... - Page 6 RPV516/RPU416 Circuit Description 1-b) Front end RF amplifier (RPU416) The input signal of antenna is applied to an RF amplifier (Q203) after passing through a transmit/receive switch circuit and a 3-grade low pass filter. The amplified signal is filtered through a band pass filter (a 3-grade LC filter) to eliminate unwanted signal before it is applied to the first mixer.
- Page 7 RPV516/RPU416 Circuit Description 5) Squelch Part of the AF signal from IC200 re-enters IC200, and the noise component is amplified and rectified by a filter and an amplifier to produce a DC voltage corresponding to the noise level. The DC signal is injected to the analog port of the microprocessor (IC403). IC403 compares the voltage with the preset value and determines whether to output sounds from the speaker.

PLL circuit 2) VCO The operating frequency is generated by Q4 in transmit mode and Q3 in receive mode. The oscillator frequency is controlled by applying the VCO control voltage, obtained from the phase comparator, to the varactor diodes (D2 and D4 in transmit mode and D1 and D3 in receive mode).
- Page 9 MUTE Fig. 6. Transmit audio CTCSS/CDCSS 4-a) RF amplifier (RPV516) The RF signal obtained from the VCO buffer amplifier Q100 is amplified by Q101 and Q102. This amplified signal is passed to the power amplifier, Q102 and Q105, which consists of a 2-stage FET amplifier and is capable of producing up to 4.5W of RF power (See Fig.
