TELEMETRY SINGLE SIDE BAND, AMPLITUDE MODULATION, ALL-SOLID-STATE, S-BAND RECEIVER DESIGN AND DEVELOPMENT PROGRAM.
SYLVANIA ELECTRIC PRODUCTS INC BUFFALO N Y
This report covers the design, development, fabrication and test of an all-solid-state, gnngle sideband microwave 2.15-2.35 gc re ceiver. The objectives of this program were realized using an all-so-dd-state approach, a 19-inch panel rack mounting assembly, syn chronous detection, r-f carrier tracking filter type ofepperation and crystal switching for channel selection. High reliability and long life under a normal laboratory envinment were stressed in the selection of design techniques and components. In the final configuration, the all-solid-state receiver employs diode switching of crystals for channel selection, triple con version, automatic frequency control, automatic phase control, crystal filtering, product demodu lation and a variable agc time constant. The receiver, when mounted in its accompanying cabinet, weighs 44 pounds and is 24 inches wide, 7-12 inches high, and 15 inches peep. Total power consumption is approximately 4 watts. This report covers the development of the receiver from its conception to its final configuration. A comparison of single sideband and other modu lation techniques is also included. In addi tion, the report highlights the areas for further investigations. Author
