For a number of communications and other applications, switched filter banks (some channelizers) and switched delay lines (phase shifters) are extremely useful since YBaCuO and TlCaBaCuO filters and delay lines have shown significant performance enhancements over their conventional counterparts, a purely superconducting version of the switched assemblies could result in additional improvements. A thermal switch has been developed that provides good isolation and insertion loss with adequate switching times to allow a monolithic approach to the switched lines and filter banks. Filter banks in the 8--11 GHz range have been demonstrated with insertion losses < 1 dB and out-of-band rejection greater than a package-limited 50 dB. Switched delay lines have been fabricated with insertion losses less than 0.3 dB/bit and peak phase deviations from linearity of less than 5 degrees over 30 GHz bandwidths.
