【摘要】 宽带功率放大器一般都存在幅频特性不均匀问题,它将直接影响系统的接收灵敏度。本文采用微带线加片状电阻的结构构成谐振器以适当吸收不同频率处的功率达到均衡目的,并提出了一种改善驻波比的方法。其特点为设计简单,加工方便,结构紧凑,成本低廉,可广泛应用于微波低频段的各种幅度均衡。更多还原

【Abstract】 A ordinary wideband power amplifier has the problem of nonuniformity of amplitude-frequency characteristic,it will directly affect the receiving sensitivity of the system.In this paper,resistor loaded microstrip resonator is used to absorb the power of different frequencies appropriately in order to balance the amplitude,and one method is mentioned to improve the VSWR(voltage standing wave ratio).The structure designed has the characteristic with simpleness,convenience,compactness and low cost,it can be widely applied to the equalizer in the low frequency of microwave.更多还原
