Compact Upconverters and Downconverters for Millimeter-Wave Communication Links

摘要

We describe a set of compact millimeter-wave frequency converters for wideband digital signals. Frequency upconverters and downconverters have been developed for frequencies from WR-28 (26–40 GHz) to WR-2.2 (325–500 GHz). Bandpass filters with passband return loss> 20dB and stopband rejection> 50dB within 1 GHz from band edges were developed for use with these upconverters. Preliminary WR-12 link tests are shown.
