Abstract
A quasioptical resonant-tunneling-diode oscillator is demonstrated at frequencies above 200 GHz. The oscillator is stabilized by a semiconfo cal open cavity. The maximum output power and the linewidth are approx imately 50 muW and 20 kHz, respectively, at a fundamental frequency of 210 GHz. By varying the cavity length, the oscillator frequency can b e adjusted over a 0.4 GHz range in a repetitive manner. This behavior is explained by analogy with laser oscillators. The quasioptical RTD o scillator is well suited as a local oscillator for low-power radiometr ic mixers.
