直接分频的6GHz锁相环的微波部分,主要包括一个FET压控振荡器,一个功分器和两个由耦合放大器连接起来的二分频器。由于6GHz的微波集成数字电路还处于研究阶段,所以混合微波电路在微波频率合成器里仍然起着主要的作用。微波分频器的同步范围超过了1GHz,并且是由集成在薄膜基片上的元件组装起来的。本文还描述了使用不同工艺时的细节。 Direct frequency division 6GHz PLL microwave part, including a FET voltage-controlled oscillator, a power splitter and two by the coupling amplifier connected to the divider. As 6GHz microwave integrated digital circuits are still in the research stage, hybrid microwave circuits still play a major role in microwave frequency synthesizers. The microwave divider has more than 1 GHz of synchronization and is assembled from components integrated into the film substrate. This article also describes the details of using different processes.
