Wide-band amplifier uses diode biased with r-f to give 40-db gain. Input impedance is above 10 gigohms, and frequency response is within 3 db from 3 cps to 200 kc. Diode D1 is energy storage element. Crystal-controlled transistor oscillator is pump frequency source.-D. Rovefi, Diode Amplifer Has Ten.Gigohm Input Impedance, Electronics, 34:51, p 38-40.
