Abstract
A GaAs single balanced mixer IC with built-in active baluns for IF and LO inputs has been developed. The present mixer achieved the conversion gain of 16 dB and the LO signal suppression over 30 dBc at the LO input power of 0 dBm. Owing to a novel BST (Barium Strontium Titanate) capacitor technology, the implemented mixer IC was packaged in the small 6 pin outline with the extremely small chip size of 0.6/spl times/0.65 mm/sup 2/. The IC can eliminate the LO filter of the up-conversion system for a variety of handyphone-sets in L-band.<>
