摘要：

本文对调频副载波（SCA）广播接收机的单片化设计进行了探讨，提出了一种新的适合CMOS工艺的全集成SCA接收机结构。接收机采用Weaver-零中频结构实现下变频和二次解调功能，节省了片外镜像抑制滤波器，大大提高了接收机的集成度，降低了接收机的成本和功耗，显示了广阔的潜在应用前景。

Abstract:

A highly integrated wireless receiver of subsidiary communication authorization（SCA）was investigated in this article. A novel fully integrated SCA receiver architecture suitable for CMOS process was proposed. The new receiver adopts Weaver-zero-IF down-conversion topology and two demodulations on chip. The external image-rejection filter is no needed and it greatly increases the integration and lowered the power consumption and cost. It shows the potential prospects of application.

Key words: subsidiary communication authorization, wireless receiver, radio frequency, zero-IF topology, weaver receiver, CMOS
