摘　　要：程控宽带射频放大器是基于同步脉冲转移原理的有线电视机顶盒的最重要的电路之一。介绍了一种程控射频宽带射频电路的设计与实现方法。该电路设计巧妙,原理简单,生产、调试与维修都非常方便。实践证明该电路工作良好,性能优良。The program controlled gain broad band radio frequency circuit is one of the most important parts of a TV topbox based on the method of synchronization pulse transfer. A method used to designing and implement a broad band RF amplifier is presented in this paper. The design method is skillful, the work principle is simple. It is convenience of producing, debugging and repairing. It is proved that the whole circuit is work well and has excellent performance.
