Abstract
Presented is a monolithic W-band (75-110 GHz) down-conversion mixer consisting of a double-balanced core, Marchand-type on-chip baluns at inputs, and a two-stage output buffer, fabricated in a 200 GHz f T SiGe technology. Including the loss for input baluns, this mixer exhibits conversion gains of 14.4 plusmn 2.8 dB and single sideband (SSB) noise figures of less than 19.5 dB across the entire W-band, drawing 28 mA from a 3.3 V supply.
