小尺寸微波晶体管放大器的设计

DESIGN OF THE SMALL SIZE MICROWAVE TRANSISTOR AMPLIFIER

通常用微带电路进行微波晶体管电路设计时,在微波的低频段,微带电路的尺寸比较大,给使用带来不便,为了缩小几何尺寸,本文着重讨论利用短微带线加以电抗支节调谐,作微波晶体管放大器级间匹配的设计方法。

A method using a short microstrip of one fourth or one eighth wavelength tuning to decrease the size of the microstrip circuit is emphatically discussed, because the dimension of the microstrip circuit at low frequency band of the microwave is inconvenient in application.
