摘要
针对传统微波开关设计和调试困难,且工作频带极窄不可调,应用范围极其受限,提出了一种基于HMC435MS8GE芯片的单刀双掷微波开关设计方法,该方法采用HMC435MS8GE开关芯片作为信号通道控制核心,并配置腔体滤波器对输出信号进行滤波,整个产品设计在一个封闭结构内,确保了信号的传输完好性,该设计在降低设计难度的同时,提高了频率的使用范围,极大地降低了调试成本,试验表明该新型微波开关设计简单、使用方便且导通损耗小,关断隔离度好,克服了传统开关的缺点,满足实际工程应用,并具有很好的推广价值。
According to the design and debugging of the traditional microwave switch is difficult,and very narrow frequency band is not adjustable,the scope of application is extremely limited,proposes a design method of SPDT microwave switch based on HMC435MS8GE chip,the method adopts HMC435MS8GE chip as the core control switch signal channel,and configure the cavity filter to filter the output signal,the entire product design in a a closed structure,to ensure the integrity of the signal transmission,the design reduces the design difficulty and improve the using range of frequency,greatly reduces the cost of debugging,experiments show that the new microwave switch has the advantages of simple design,convenient use and low conduction loss,turn off good isolation,to overcome the traditional switch shortcomings,meet the actual engineering application,and has good popularization value.
