Abstract

PURPOSE:To facilitate the setting of an optimum matching point by using a 4-terminal 3dB directional coupler for input/output, and connecting it with input/ output terminals. CONSTITUTION:An fa wave inputted from the UP side is branched by a branching filter 1a and inputted to a terminal A of an amplifier section, the fa wave inputted from the terminal A is branched into two (phase difference is 180 deg.), inputted to an amplifier section 3, and the amplified fa wave by the amplifier is inputted to a directional coupler 2b. The inputted fa wave is sent from a terminal O only by the characteristic of the directional coupler. Since the unmatched component from the amplifier or the like is outputted from a terminal C, the optimum setting is attained easily by minimizing the sending component to the terminal C among the input from the terminal A. The wave fa outputted from a terminal D is led to the DOWN side by a branching filter 1b and sent. Similarly, the fb wave inputted from the DOWN side passes through the branching filter 1b, is inputted to an amplifier section from a terminal B, outputted to the terminal C and sent toward the UP side by the branching filter.
