2.10 VHF Receiver

The VHF receiver consists of front end, back end, and automatic gain control circuits. A block diagram
of the VHF receiver is shown in Figure 2-10. Detailed descriptions of these features are contained in
the paragraphs that follow.

VHF Receiver Block Diagram

2.10.1 Receiver Front-End

The RF signal is received by the antenna and applied to a low-pass filter consisting of L3531, L3532,
C3532 to C3536. The filtered RF signal is passed through the antenna switch. The antenna switch
circuit consists of two PIN diodes (D3521 and D3551) and a pi network (C3531, L3551 and
C3550).The RF signal is then applied to a varactor tuned bandpass filter which consists of L3301,
L3303, C3301 to C3304 and D3301. The filter is tuned by applying a control voltage to the varactor
diode (D3301) in the filter.

The bandpass filter is electronically tuned by the DACRx from IC U404 which is controlled by the
microprocessor. Depending on the carrier frequency, the DACRx supplies the tuning 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 Q3302 via C3306. After
being amplified by the RF amplifier, the RF signal is further filtered by a second varactor tuned
bandpass filter, consisting of L3305, L3306, C3311 to C3314 and D3302.

Both the pre and post-RF amplifier varactor tuned filters have similar responses. The 3 dB bandwidth
of the filter is about 12 MHz. This enables the filters to be electronically controlled by using a single
control voltage which is DACRx.
