摘要
针对静态分频器工作频率越高功耗越大的问题,本文采用GaAs HBT工艺研究设计了高性能动态分频器。通过对动态分频器结构进行研究,采用有源负载代替传统的电阻负载,提高了分频器工作的频率。同时对动态分频器进行电路设计,并对其进行仿真,得出其分频范围为9~15 GHz,具有良好的输入灵活度,功耗仅为130.26m W,满足设计要求。
Aiming at the problems of static frequency divider frequency fiigher the greater the power. In this paper, the GaAs HBT process of high performance dynamic frequency divider is designed. Through the study on the dynamic frequency divider structure, with active load instead of traditional resistive load, improve the frequency divider work. Also on dynamic frequency divider for circuit design, and carries on the simulation, it is concluded that the frequency range with good flexibility of input 9 15GHz, power only for 130.26mW and meet the design requirements.
