DESIGN OF SINGLE DIODE WIDEBAND PARAMETRIC AMPLIFIERS OF SPECIFIED GAIN, BANDWIDTH, AND SIGNAL LOAD IMPEDANCE

Abstract

Design procedure is described for fixed-frequency wideband parametric amplifiers which utilize a single varactor diode and operate in the threefrequency mode: f sub p=f+f'. The procedure is applicable to designing with lumped and/or distributed circuit elements. The circuit is oneANALYZED BY Matthaei and is achieved by the synthesis of appropriate signal and idler bandpass filters from a low-pass prototype. The design procedure is for specified but arbitrary signal, midband gain C sub SO, (Fractional) bandwidth w sub D, and signal filter midband impedance R sub bo. One result of developing design equations for arbitrary R sub bo is that the transformer between R sub bo and R sub c is now eliminated by simply assigning R sub bo equals R sub c. Numerical examples of designs are given for degenerate and non-degenerate microwave amplifiers. (Author)
