A 60 GHz wideband quadrature-balanced down-conversion mixer employing a new wideband technique with an active feedback has been developed in this work. Fabricated with a 0.13 μm RFCMOS technology, the mixer exhibits a 3 dB IF bandwidth of 5 GHz with a conversion gain of 2.3 dB for a fixed LO frequency of 60 GHz. The mixer also shows an RF bandwidth of 7 GHz with a peak gain of 5.6 dB at 55 GHz. The circuit draws 10.6 mA from 1.3 V supply.
