Abstract:

A telemetry receiver having remote tuning capability and a direct coupled video output. A VHF reference of the desired frequency is synthesized in a programmable closed loop around a varactor tuned oscillator. The VHF reference is fed back through programmable frequency dividers and referenced to a crystal controlled oscillator to adjust the frequency of the varactor tuned oscillator to the desired frequency. The synthesized VHF reference in then coupled to one port of a double balanced mixer which has the received RF signal as its other input. The output of the balanced mixer is converted to IF and fed to an AMFM demodulator to provide AM and FM signal outputs.
