  • Semipassive responder utilizing a low voltage, low power drain reflective varactor phase modulator
    Patent number: 3996587
    Abstract: A semipassive responder for use in a communication system wherein an interrogating unit transmits an interrogation signal to illuminate the responder. The responder generates, in response to incident interrogation signals, a phase-coded reply signal, utilizing a low voltage, low power-drain reflective varactor phase modulator.

  • Two-inductor varactor tunable solid-state microwave oscillator
    Patent number: 3984787
    Abstract: A two-inductor varactor tunable solid-state microwave oscillator comprising a series tunable circuit wherein one inductor is serially connected with a negative resistance active element, an impedance load, and a varactor. The circuit is tuned by changing the reactance of the circuit by varying electrically the capacitance of the varactor. The second inductor is connected in parallel with the varactor to increase the range of reactance change of the series circuit effected by the variation in capacitance of the varactor to provide thereby for a wider frequency tuning range.
