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 pff. The procedure is applicable to designing with lumped andor 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
