Abstract:
1. An arrangement for controlling the output power of a high-frequency transmitter comprising: a digital signal processor (P) generating baseband components (I and Q) for modulation onto a high-frequency carrier (T), said digital signal processor (P) also generating an output signal (S) corresponding to an instantaneous desired output power of said high-frequency transmitter; a comparator (K) for generating a control signal (R) by comparing the output power of a power amplifier (L) with said output signal (S); and an I/Q modulator (M) for controlling input power to said power amplifier (L); wherein output power of said I/Q modulator (M) is dependent on said control signal (R); wherein input power to said power amplifier comprises said output power of said I/Q modulator (M); and wherein output power of said high frequency transmitter is dependent on said control signal (R).
