1. Receiver Circuit 

The FM dual-conversion super heterodyne receiver is designed for operation in the 

136-174 MHz

 frequency 

range. The Receiver has intermediate frequencies (IF) of 115.65MHz and 450kHz. Adjacent channel 

selectivity is obtained by using two band pass filters, a 115.65MHz crystal filter and a 450kHz ceramic filter.   

The RX detector is the phase digitizer.   

 

1-1 Receiver Front-end 

A RF signal from antenna is coupled though the low pass filter/antenna switch, and band pass filter to the input 

of low noise amplifier Q101. The output of Q101 is coupled through band pass filter to input of 1’st Mixer 

Z101. Front End selectivity is provided by these band pass filter. 

 

1-2 1’st Mixer 

The 1’st Mixer is a Double-Balanced-Mixer Z101, that converts a RF signal the 136-174MHz range to 

115.65MHz 1’st IF frequency. The signal on the output of Z101 is provided to the input of 1’st IF amplifier 

Q102.  

 

1-3 1’st IF 

The 1’st IF signal 115.65MHz from the output of the 1’st Mixer is coupled through 1’st IF amplifier Q102 to 

Crystal filter FL103. The highly-selective crystal filter FL103 provide the first portion of the receiver IF 

selectivity. The output of the filter is coupled through the impedance-matching net work to IF Receiver U101.

 

 

1-4 2nd Mixer, 2nd IF filter and 2nd IF amplifier 

IF Receiver U101 is an one-chip IC for digital communication system. It includes 2’nd Mixer, 2’nd IF 

amplifier and Limiter amplifier. With the internal circuits of U101, The 1’st IF signal is amplified and applied 

to the input of 2’nd Mixer. The 2’nd local injection frequency 115.2MHz is applied from 2’nd local amplifier 

Q106 to another input of the 2’nd Mixer. The 2’nd Mixer converts a 1’st IF signal 115.65MHz to 2’nd IF 

frequency 450KHz. Then the 2’nd IF signal is applied to Ceramic Filter FL105(Wide Band) or FL106 (

Narrow 

Band&C4FM

), which provides the 450KHz selectivity. Those IF filters are controlled by IF.NARROW signal 

from the microcomputer (HILLARY:U700).

 

The output of the 2’nd IF filter is applied through 2’nd IF
