Abstract :
The design, fabrication, and testing of hybrid semiconductive/high-temperature superconductive (HTSC) Ku-band microwave integrated circuits (MICs) operating at cryogenic temperatures are described. The first cooled feedback oscillators using GaAs FET monolithic microwave integrated circuit (MMIC) los-noise amplifiers for gain and a high-Q TlBaCaCuO linear resonator for stabilization is presented together with a low-noise high electron mobility transistor (HEMT) amplifier using TlBaCaCuO distributed stubs for matching. Both demonstrate that HTSC and semiconductive elements can be successfully integrated.<>
