本文较详细地叙述了收发开关限幅器设计中应当考虑的一些问题,以及如何解决这问题,并给了设计公式。随着工作频率的升高,微波开关管和限幅管的杂散参量的影响越来越大,使它们的开关和限幅性能显著下降,甚至丧失,在开关接通和小信通过限幅器时,匹配更加困难,所以在设计中必须考虑杂散参量的影响,并设法消除它们的影响。本文用串联 This article describes in detail some issues that should be considered in the design of the transmit / receive switch limiter and how to solve the problem, and gives the design formula. With the increase of the working frequency, the influence of the spurious parameters of the microwave switching tube and the limiting tube is more and more large, so that their switching performance and limiting performance are significantly reduced or even lost. When the switching is on and the small letters pass the limiting Matching is more difficult, so the design must consider the effects of stray parameters and try to eliminate their effects.
