Abstract
A microwave frequency discriminator using a one port active device amplifier including a circulator for coupling an input RF signal of substantially constant power level into the amplifier and an output RF signal out from the amplifier. The discriminator further comprises input and output matching networks connected to the circulator and a detector for generating a D.C. signal as a function of the incoming signal frequency. The input and output impedance matching networks are formed to provide selected impedance conditions to the amplifier such that the power-frequency response of the amplifier varies substantially linearly approximating a frequency discriminator characteristic throughout a predetermined frequency bandwidth.
