A K-band distributed frequency doubler is developed in 0.18 mu m CMOS technology. This doubler combines the distributed topology for broadband characteristics and current-reuse technique to improve the conversion gain. The high-pass drain line and high-pass inter-stage matching network are used to obtain a good fundamental rejection. A measured conversion gain of better than -12.3 dB is obtained, and the fundamental rejection is better than 30 dB for the output frequency between 18 and 26 GHz. The dc power consumption is 10.5 mW with a chip size of 0.55 x 0.5 mm(2).
