DEVELOPMENT OF EXPERIMENTAL ELECTRONICALLY TUNED, DECADE-BANDWIDTH RECEIVER.
Abstract
Efforts concerned a program to develop an experimental model of a tunable receiver operating between 300 and 3000 mc. The resulting receiver can be either manually tuned across its range or electronically swept over sectors ranging from 2 mc to the full decade bandwidth at any rate up to 100 cps. The receiver has a sensitivity of better than -90 dbm over its full operating range, a saturation level of +10 dbm, an instantaneous 3-db bandwidth of 2.05 mc and a 60-db bandwidth of 10 mc--all satisfying the original specification. The essentially solid-state receiver basically consists of a low-pass input filter, upconverter and associated X-band pump circuit, bandpass filter, tunnel-diode amplifier, downconverter, and I-F amplifier-detector. Experience gained during the program showed that it is practical to use the same techniques for the 30- to 300-mc frequency range. (Author)
