Abstract :
This paper demonstrates a W-band CMOS frequency doubler which utilizes a balanced topology in order to achieve a wideband fundamental suppression. The required 180-degree phase shift is obtained by employing a spiral transmission line balun. At 100 GHz the measured conversion loss of the frequency doubler is 16 dB using an input power of +5 dBm. The fundamental suppression is better than 25 dB from 42 to 55 GHz.
