Abstract :
In this paper, a K-band frequency doubler with a tunable input matching network and LC reflector is first proposed and implemented using 0.18-μm CMOS process. The conversion gain bandwidth is extended by the tunable input matching network and the tunable LC reflector can improve the fundamental rejection. This frequency doubler exhibits a conversion gain of -6~-8.3 dB from 18 to 26 GHz with 0 dBm input power and fundamental rejection of 32.5 to 44 dB. The dc power consumption is only 5.4 mW with a chip size of 0.55 × 0.46 mm2.
