摘要

提出了一种适用于毫米波图像抑制接收机的宽带多相RC滤波器。环形布局优于传统的网格布局，以提高对称性。交叉路径在微带和反向微带中实现，具有高隔离性。电磁仿真结果表明，在20 ~ 50 GHz范围内，增益不平衡小于1.0 dB，相位不平衡小于1.4°。

A polyphase RC filter implemented in ring configuration for a SiGe millimetre-wave receiver

A broadband polyphase RC Filter is presented suitable for millimetre-wave image reject receivers. A ring layout is chosen in preference to the traditional grid layout to improve symmetry. Crossover paths are implemented in microstrip and inverted microstrip with high isolation. Electromagnetic simulation shows a gain imbalance less than 1.0 dB and phase imbalance less than 1.4° from 20 to 50 GHz.
