参量放大器参量放大器parametricamplifier利用时变电抗参量实现低噪声放大的放大电路。例如，在变容二极管的两端外加一个周期交变电压时，其电容参量将随时间作周期变化。若把这一时变电容接入信号回路中，且当电容量变化和信号电压变化满足适当关系时，就能使信号得到放大。外加的交变电压源称为泵浦源。利用铁芯非线性电感线圈和电子束的非线性等也能构成参量放大器。参量放大的原理在20世纪30年代就已出现，但直到50年代后期，可在微波频段工作的半导体变容二极管问世以后才得到发展。这是因为变容二极管具有很高的Q值，适于制作噪声电平极低的微波放大器。变容管参量放大器主要用来放大频率约为1～50吉赫之间的微弱信号。在这个频率范围内，它的噪声特性略差于量子放大器，但结构简单，维护也很方便。变容管参量放大器按工作方式区分，有负阻式放大器和上变频式放大器两大类。前者可分为信号频率和空闲频率大致相等的简并式放大器（这时信频回路可兼作闲频回路）和不相等的非简并式放大器。上变频式参量放大器实际上是一个有增益的参量变频器。
