Abstract:
This paper describes a new all solid state airborne low level PAM multicoder that employs N-channel FET for all the analog switching functions of the system. The unit features a 72KHz true chopper amplifier that affords complete isolation between input and output. This unit is fully developed and went into production in June 1966 offering many advanced features to airborne telemetry system users. Each input channel presents a true differential analog switch into the low level D. C. amplifier. The operating characteristics such as C. M. R. (100 db) out to 1KHz, no D. C. drift or gain-change, and selectable pedestal levels add to ease of operation and flexibility. Heavy use of integrated circuits was also made including monolythics, hybrids and discrete elements. The gating logic, chopper amplifier front end, and carrier amplifier/synchronous demodulator each have a separate power supply winding thus providing excellent isolation for user applications. Mechanical construction employs plug in boards affording ease of manufacture and complete interchangeability of boards between units. The system is discussed as to unique features and techniques necessary to build the unit and satisfy stringent specifications.
