CIRCUIT DESCRIPTION /

!

Frequency Configuration

The receiver utilizes double conversion. The first IF is

49.95MHz and the second IF is 450kHz. The first local oscil-
lator signal is supplied from the PLL circuit.

The PLL circuit in the transmitter generates the necessary

frequencies. Figure 1 shows the frequencies.

Receiver System

The receiver is double conversion superheterodyne. The

frequency configuration is shown in Figure 1.

■

Front-end RF Amplifier

An incoming signal from the antenna is applied to an RF

amplifier (Q353) after passing through a transmit/receive
switch circuit (D603, D604 are off) and a band pass filter
(L357, L356 and varactor diodes : D353, D354). After the
signal is amplified (Q353), the signal is filtered through a band
pass filter (L354, L355 and varactor diodes: D351, D352) to
eliminate unwanted signals before it is passed to the first
mixer.

The voltage of these diodes are controlled by tracking the

CPU (IC101) center frequency of the band pass filter. (See
Fig. 2)

■

First Mixer

The signal from the RF amplifier is heterodyned with the

first local oscillator signal from the PLL frequency synthesizer
circuit at the first mixer (Q352) to create a 49.95MHz first
intermediate frequency (1st IF) signal. The first IF signal is
then fed through one pair of monolithic crystal filter (MCF :
XF351) to further remove spurious signals.
