Abstract :
A monolithically integrated mixer based on a Gilbert cell multiplier for ultra-broadband applications has been produced in self-aligning 1 mu m silicon bipolar technology. Positive power conversion gain bandwidths for RF and LO up to 17.3 GHz and for the intermediate frequency (IF) up to 13 GHz were measured. The corresponding -3 dB frequencies are 9 GHz for RF and LO (IF=100 MHz) and 8 GHz (fLO=1 GHz) for IF.
