A low phase-noise 38-GHz HBT MMIC oscillator utilizing a novel transmission line resonator

Abstract

This paper reports on a low phase noise 38 GHz-band HBT MMIC oscillator employing a newly proposed transmission line resonator. The achieved phase noise of -114 dBc/Hz at 1 MHz offset is believed to be the lowest reported for millimeter-wave oscillators without a dielectric resonator.
