A device that amplifies microwave bands. When a nonlinear reactance such as a variable capacitance diode, whose capacitance changes with the applied voltage, is excited by a high frequency fp called a pump , and a lower frequency signal f1 is applied to it, the power p applied from fp is distributed to two frequencies , f1 and fp - f1 , in the ratios pf1/fp and p ( fp - f1 ) / fp . In the end, the power of fp is transferred to the f1 signal, which has a negative resistance type amplification effect . The power of fp - f1 is absorbed by a resonant circuit called an idler.

マイクロ波帯の増幅を行う装置。印加電圧によって容量が変化する可変容量ダイオードなどの非線形リアクタンスをポンプと呼ばれる高周波fpで励振しておき,これにf1という,より低い周波数の信号を加えると,fpから加えた電力pはf1とfp-f1の二つの周波数にpf1/fpとp(fp-f1)/fpの割合で分配される。結局f1の信号にfpの電力が乗り移ったことになり,負性抵抗形の増幅作用をもつ。fp-f1の電力はアイドラーと呼ばれる共振回路で吸収する。
