The first fully integrated HTS millimeter‐wave oscillator operating at 77 K with a phase noise improvement of 20 dB over conventional oscillators is reported. A loaded Q of 59,000 at 36.5 GHz obtained from a sapphire resonator shielded by HTS ground planes is almost 100 times greater than ceramic resonators. © 1993 John Wiley & Sons, Inc.
