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 (Display models only) – 8 characters (14 segments star burst) and 10 icons with back- lighting, liquid-crystal display (LCD). Keypad Board (Display models only) – Display model: 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.Figure 2-1.

December 3, 2003HKLN4215A 2-2Theory Of Operation: Major Assemblies The IFIC is a low-voltage monolithic FM IF system incorporating a mixer/oscillator, two limiting IF amplifiers, quadrature detector, logarithmic received signal strength indicator (RSSI), voltage regulator and audio, and RSSI Op Amps. The second LO frequency, 44.395 MHz, is determined by a crystal oscillator. The second mixer converts the 44.85 MHz high IF frequency to 455 kHz. Additional IF selectivity is provided by two ceramic filters. The first ceramic filter is a 4-pole filter used between the second mixer and IF amp. The second ceramic filter is a 6-pole filter and is used between the IF amp and the limiter input. For the second ceramic filter, a wider filter is used for 20/25 kHz channel spacing, and a narrower filter is used for 12.5 kHz channels. A ceramic resonator provides phases vs. frequency characteristic required by the quadrature detector, with 90 degree phase shift occurring at 455 kHz. The output of the IFIC is the recovered audio signal which is fed to the audio IC for amplification and signal conditioning. The output of the audio IC is injecting into the audio PA which drives the 24 Ohm speaker. 2.2.2 Transmitter When the radio is transmitting, microphone audio is passed through the audio IC, where pre- emphasis and low-pass (splatter) filtering are done. The output of the audio IC is used to modu- late the TX VCO, which creates the modulated carrier. The modulated carrier is then amplified by the pre-driver and power amplifier circuit, which transmits the signal under dynamic power control Figure 2-2.
