Linear Integrated Circuits in a Channelized High-Frequency Receiver

摘要

An application of modern linear integrated circuits to the design of a channelized high-frequency radio receiver is presented. The results of testing a prototype, crystal-controlled, fixed-tuned integrated-circuit receiver front end and wideband frequency-conversion stage are shown. Probelms of image rejection with single frequency conversion are discussed. The design of a channelized receiver section using modern special-purpose linear integrated circuits is shown. (Author)
