PROBLEM TO BE SOLVED: To provide a constant-amplitude wave combination type amplifier which allows a device to be miniaturized and is capable of reducing cost. SOLUTION: The constant-amplitude wave combination type amplifier includes a first amplifier 3a for amplifying one of signals into which a distributor 1 distributes an input signal, and a second amplifier 3b for amplifying the other and combines the output signals from the first and second amplifiers 3a and 3b of two systems by a combiner 2 and outputs the combined result. The first and second amplifiers 3a and 3b comprise at least two amplifying elements incorporated into a single package. The amplifying elements constituting the first and second amplifiers 3a and 3b, respectively are mounted, in close contact with each other. The amplifying elements, constituting the first and second amplifiers 3a and 3b respectively, are constituted by using field effect transistors or bipolar transistors. COPYRIGHT: (C)2008,JPO&INPIT
