Abstract :
A high-temperature superconducting four-channel filterbank was fabricated and tested. The device was made in microstrip configuration with an architecture that included two branch-line hybrids and two identical parallel-coupled line filters per channel. The filterbank was fully integrated, with microstrip interconnections between channels and thin-film load terminations in the out-of-phase port of the output hybrid.<>
