Solid State EMC Technology Development.

Abstract

Critical superheterodyne receiver parameters were studied and evaluated to extend the dynamic range and reduce the spurious responses of UHF receivers operating in a high-level RF environment. An up-conversion receiver front end using a surface acoustic wave filter for initial IF selectivity was assembled and evaluated. A single conversion receiver was evaluated using high-level, low-distortion elements. Also, a low-noise, high-level, synthesizer/VCO was designed for receiver local oscillator injection and transmitter frequency excitation. A solid state transmitter was modified to minimize the spurious output and broadband noise levels. A solid state demonstration receiver/transmitter suitable for airborne testing was assembled using the optimized circuits and electrical tests were made on the completed transceiver. (Author)
