Period
CTS/HERMES PROGRAM WAS INITIATED IN 1971 & SATELLITE OPERATED FROM JAN. 17, 1976 TO NOV. 24, 1979.
Canada
FET (FIELD EFFECT TRANSISTOR) AMPLIFIERS WERE DEVELOPED FOR CTS/HERMES 14/12 GHZ TRANSPONDER BY CRC FROM 1972-1974 & TECHNOLOGY WAS TRANSFERRED TO INDUSTRY. SED DID NOT CONTINUE TO PRODUCE THESE BECAUSE JAPANESE TOOK OVER MARKET/ CTS/HERMES WAS CANADIAN DESIGNED & BUILT SATELLITE WHICH EXPLORED USE OF HIGH POWER TRANSPONDERS AT HIGHER FREQUENCIES TO EXPAND COMMUNICATIONS CAPABILITIES IN NORTHERN AREAS.
Function
Unknown
Technical
CRC USED MICROWAVE INTEGRATED CIRCUIT TECHNOLOGIES & EXPERIMENTAL DEVICES TO DEVELOP FIRST FET AMPLIFIERS FOR SPACEAPPLICATIONS. THEIR USE BECAME COMMONPLACE IN SATELLITES AT BOTH 14/12 & 6/4 GHz AS WELL AS IN GROUND TERMINALS (REF 1). THIS WAS SECOND GENERATION UNIT DEVELOPED BY SED UNDER DOC CONTRACT.
