摘要

讨论了一种实现直接微波QAM调制器的新方法。该架构使用SPDT开关和引脚二极管反射衰减器来实现QAM调制器。衰减器在正向偏置条件下使用引脚二极管来克服速度限制。这种转换架构提供了一个高速QAM调制器，并使用Si-MMIC实现了无线系统的成本效益和高性能调制器。

A low-cost direct microwave QAM modulator using silicon MMIC technology

A new method to realize a direct microwave QAM modulator is discussed. The architecture uses SPDT switches and pin diode reflection attenuators to realize a QAM modulator. The attenuators use pin diodes in a forward bias condition to overcome the speed limitation. This slew architecture provides a high speed QAM modulator, and its implementation using Si-MMIC results a cost efficient and high performance modulator for wireless systems.
