Abstract
A linearizer circuit is described having a main radio frequency or intermediate frequency network and secondary baseband frequency network. The main network includes a directional coupler, a delay line, a phase modulator and an amplitude modulator. The secondary network includes means for amplitude detecting and filtering an input signal and a pair of adjustable-gain amplifiers which receive the amplitude detected signal and on the basis of the gain adjustment act on the two modulators as to give them nonlinear response curves so as to compensate for the nonlinearity of the power amplifier placed downstream from the linearizer.
