摘要： PROBLEM TO BE SOLVED: To obtain radio communication equipment capable of adjusting transmitting power with high accuracy by synchronizing a burst signal to be inputted with ALC (auto level control) switching and performing ALC between when only the burst signal is transmitted and when a continuous signal and the burst signal are mixed and transmitted.
SOLUTION: A comparison determining part 16 compares an input power value P1 with an input reference value Pin, and determines that an input signal exists when P1 becomes equal to or greater than Pin. A comparison determining part 18 compares a transmitting power value P3 at the preceding control time stored in a memory 17 with a transmitting power value P2 at the present control time, determines whether a decreased amount (P3-P2) becomes equal to or greater than a prescribed value and determines whether an increased amount (P2-P3) becomes equal to or greater than a prescribed value. A first gain control part 20 and a second gain control part 21 command a gain control amount to a variable gain device 4 on the basis of these determination results.

摘要： PROBLEM TO BE SOLVED: To solve the problem wherein since existing distortion compensation circuits perform individual distortion compensation considering nonlinearity of an amplifier, followed by recombination, on a plurality of modulation wave signals with different center frequencies, an intermodulation distortion occurs between the plurality of modulation waves in the amplifier module.SOLUTION: A distortion characteristic of an amplifier is determined beforehand. A control section controls a distortion compensation circuit to match appropriate distortion compensation with a plurality of input frequencies. The distortion compensation circuit performs distortion compensation under the control of the control section.
