TELEMETRY SINGLE SIDE BAND, AMPLITUDE MODULATION, ALL-SOLID-STATE, S-BAND RECEIVER DESIGN AND DEVELOPMENT PROGRAM

摘要

This report covers the design, development, fabrication and test of an all-solid-state, single sideband microwave (2.15-2. 35 gc) receiver. The ob¬jectives of this program were realized using an all-solid-state approach, a 19-inch panel rack mounting assembly, synchronous detection, r-f carrier tracking filter type of operation and crystal switching for channel selection. High reliability and long life under a normal laboratory environment were stressed in the selection of design techniques and components.nIn the final configuration, the all-solid-state receiver employs diode switching of crystals for channel selection, triple conversion, automatic frequency control, automatic phase control, crystal filtering, product demodu¬lation and a variable age time constant. The receiver, when mounted in its accompanying cabinet, weighs 44 pounds and is 24 inches wide, 7-1/2 inches high, and 15 inches deep. Total power consumption is approximately 4 watts.
