Abstract:

This report describes the work accomplished during the first quarterly period in the effort to eventually produce silicon linear integrated circuits of the type used in FM receivers. Most of the effort was devoted to developing the receiver back-end circuits i.e., the circuits the follow the i-f filter. During the first quarter, circuits designed to replace the IC500 i-f amplifier, IC501 limiter, IC502 squelch, and IC503 audio amplifier were breadboarded and tested. The receiver back-end circuits are comprised of three integrated circuits, as outlined below, and a conventional circuit discriminator. 1 IF Amplifier The four i-f amplifier stages are to be packaged in two TO-5 cans with two amplifier stages occupying the same chip. 2 LimiterSquelch Occupying the same chip will be the limiter, squelch noise amplifiers, and the squelch switch. 3 Audio Amplifier A class B push-pull amplifier was selected after careful comparison with a class A amplifier.
