Patent ID: 7305046

Claim:
An I/Q modulator for processing an I/Q signal so as to obtain a predistorted output signal, said I/Q signal having an I component and a Q component, comprising: a predistorter for predistorting, with a predistortion signal, a carrier signal having an angular frequency, the carrier signal comprising a first subcomponent having the angular frequency and a second subcomponent having the angular frequency, the second subcomponent being substantially orthogonal to said first subcomponent, so as to obtain a first and a second predistorted subcomponent of the carrier signal, said predistortion signal depending on the I component and the Q component; a first multiplier for multiplying the I component by the first predistorted subcomponent so as to obtain a multiplied I component; a second multiplier for multiplying the Q component by the second predistorted subcomponent so as to obtain a multiplied Q component; an adder for adding the multiplied I component and the negative multiplied Q component so as to obtain the predistorted output signal.
