Patent ID: 8587378

Claim:
An analog pre-distortion linearizer having predetermined gain and phase characteristics as a function of input RF signal power, said linearizer comprising: a core circuit comprising: an input terminal configured to receive an input RF signal; an output terminal configured to provide a processed version of said input RF signal; a transistor having a gate, a drain and a source, said gate being connected to said input terminal, and said drain being connected to said output terminal; and a feedback circuit connected to said transistor, said feedback circuit being configured to present an impedance at the frequency of said input RF signal; wherein a first dc bias voltage applied to said gate and a second dc bias voltage applied to said drain are selected to cause said transistor to operate at a quiescent bias point in a saturated region of the transistor I-V plane; and wherein said quiescent bias point and said impedance are selected such that said linearizer has said predetermined gain and phase characteristics as a function of RF signal power.
