Chapter 2 Theory Of Operation

2.1

Introduction

This chapter provides a basic theory of operation for the radio components.

2.2

Major Assemblies

• Transceiver Board – contains all transmit, receive, and audio circuitry.
• Display (Limited and Full Keypad models only) – 8 characters (14 segments star burst) and 10 

icons with backlighting, liquid-crystal display (LCD).

Keypad Board (Limited and Full Keypad models only) –
Limited Keypad: a 2-button menu keypad with 2-way navigation button,
Full Keypad: a 2-button menu keypad with 2-way navigation button, and a 3 x 4 alphanumeric 
keypad.Transceiver Board (

Figure 2-1

).

2.2.1

Receiver

Incoming RF signals from the antenna are first routed through the harmonic filter and antenna 
switch, part of the transmitter circuitry, before being applied to the receiver front end. The receiver 
front end consists of a preselector filter, RF amplifier, interstage filter, and a double-balanced first 
mixer (

Figure 2-2

).

The mixer output is applied to a diplexer network which matches the 44.85 MHz IF signal to the 
crystal filter, and terminates the mixer into 50 ohms at all other frequencies.

The receiver back-end is a dual conversion design. High IF selectivity is provided by a 4-pole 
fundamental mode 44.85 MHz crystal filter. The output is matched to an IF amplifier stage. The 
output of the IF amplifier is applied to the input of the receiver IFIC.
