Balanced V-band DC-biased mixer with wide (12-GHz) RF/IF bandwidth

A description is presented of the design and performance of the first balanced DC-biased millimeter-wave mixer with a wide (12-GHz) instantaneous RF/IF bandwidth. Relative to prior mixers, this mixer requires less local oscillator (LO) drive and yet provides the superior intermodulation suppression provided by a balanced design. The mixer includes a unique IF output filter which avoids the reentry problems associated with conventional high/low-Z/sub 0/ designs. The mixer design is applicable to a new generation of electronic warfare systems which cover wide millimeter-wave bands with a small number of mixers and shared LOs.<
