High Data Rate W-Band Balanced Schottky Diode Envelope Detector for Broadband Communications

This article reports on a W-Band (75–110 GHz) Schottky diode based balanced envelope detector in microstrip technology, featuring a transition from WR-10 to microstrip. The manufactured detector provides 20 GHz of input RF bandwidth within the W-band. A video bandwidth between 4 GHz and 6 GHz is achieved for input RF frequencies between 75 GHz and 88 GHz, allowing error free transmission of signals up to 12 Gbit/s.
