Abstract: An RF oscillator and modulator especially useful for UHF applications. The oscillator may comprise a series-tuned Colpitts circuit with the tuned circuit including microstrip transmission lines as impedance elements. The modulator includes a pair of serially connected diodes with the common terminal of the diodes receiving a modulation signal which varies the total current through the diodes. The diodes function as current-variable resistances to attenuate the carrier frequency signal in response to the modulation signal.
