Phased Array Components for the High Temperature Superconducting Space Experiment (HTSSE)

Abstract

A new class of X-band phase shifters using the distributed Josephson inductance (DJI) effect were delivered to NRL for the HTS Space Experiment project. Phase shifts were observed above 77 K, and large phase shifts were observed at 65 K and below. This narrow-band device was developed as a first step to a broadband device. A total of 40 HTS SQUIDs were successfully integrated into a monolithic circuit. Measurement of the temperature dependance of the Q of a resonator in June 1990 and in February 1991 showed no significant change due to aging. A total of seven X-band phase shifters were fabricated, and five were delivered to Naval Research Laboratory. The HTS phase shifter consists of a low loss YBa2Cu3O7 microstrip resonator with 40 SQUID devices monolithically imbedded into the transmission line. This narrow-band device was developed as a first step to a broadband device.
