Abstract:
A wireless communication apparatus comprising:transmission power designating means for designating transmission power of a transmission signal to be transmitted from said wireless communication apparatus; controlling reference value producing means for producing a reference value used to control transmission power based upon said designated transmission power; timing control means for defining control timing of said transmission power; error detecting means for detecting an error based upon a difference value between a detection value obtained by detecting the transmission signal of said wireless communication apparatus and a detection value of a transmission signal when said transmission signal is transmitted under said designated transmission power; gain multiplying means for multiplying said detected error by a predetermined gain to obtain a correction value; control amount producing means for producing a feedback control amount based upon said correction value; power adjusting means for again setting a gain in a transmission power amplification at said control timing based upon said reference value for controlling the transmission power and said feedback control amount so as to adjust the transmission power; power amplifying means for power-amplifying said transmission signal; current consumption adjusting means for adjusting a current consumption in such a manner that a bias voltage is applied to said power amplifying means in response to said designated transmission power so as to control a bias current in said power amplifying means; and gain variation compensating means for compensating a variation in gains when the variation of said gains occurs in the transmission power amplification by controlling said bias current.
