摘　　要：基于0.18μm SiGe BiCMOS工艺,设计实现了一种可编程高速宽带分频器电路,分析了分频器实现高频宽带的方法。提出了一种模值可切换的/4/5、/8/9前置分频器结构和CML差分结构的M/A计数器,实现了宽工作频带。实测验证结果表明,该分频器工作频率可覆盖1~10 GHz,整个频带射频输入灵敏度均低于-10dBm。A programmable high speed and wideband frequency divider was designed and implemented in a 0.18μm SiGe BiCMOS process.The methods for optimizing high and wideband frequency was analyzed for the divider.A/4/5or/8/9prescaler with switchable module value and a M/Acounter based on CML difference structure were proposed,which achieved a wideband working frequency.The measurement results showed that the operating frequency of the divider could cover 1~10 GHz,and the RF input sensitivity of the whole band was lower than-10dBm.
