Abstract
A device comprising a microstrip including a narrow conductor connected in series between a circuit input terminal and the power amplifier, a film of ferrimagnetic material positioned adjacent the conductor and magnetic biasing means. The biasing means normally biases the ferrimagnetic material to operate at frequencies about a selected center frequency for nonlinearly enhancing RF input signals as a function of input amplitude. The device normally, undesirably provides nonlinear phase shifts to the input signal as a function of input power at frequencies removed from the center frequency. By choice of the amount of the bias, for a particular input signal frequency, the device can be adjusted to produce phase shift which changes as a function of input power to offset the nonlinear phase shift of the RF amplifier.
