摘要

开发了一种内置中频和本振输入有源平衡的GaAs单平衡混频器IC。本混频器在LO输入功率为0 dBm的情况下实现了16 dB的转换增益和30 dBc以上的LO信号抑制。由于采用了新颖的BST(钛酸钡锶)电容器技术，所实现的混频器IC封装在6引脚的小轮廓中，芯片尺寸极小，仅为0.6/spl倍/0.65 mm/sup 2/。该集成电路可以消除l波段各种手持电话上转换系统的LO滤波器。

A GaAs single balanced mixer MMIC with built-in active balun for personal communication systems

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.<>
