This paper presents a 6 to 64 GHz passive distributed drain mixer implemented by using a standard 0.13 um CMOS process. To improve the bandwidth, low conversion loss and low noise figure, filtering structures is utilized for wideband matching. Both Chebyshev and Butterworth filters are used instead of the classical constant-k sections of the conventional DA in order to form respectively the gate and drain transmission lines. This mixer consumes zero dc power and exhibits a conversion loss of 4.9-7.9 dB and noise figure (DSB) of 6.8-8.1 dB from 6 to 64 GHz.
