Abstract

PURPOSE:To improve the electric characteristic by forming directional couplers, amplifiers and connection lines on two bases at both sides of a ground conductor separately respectively so as to halve the size and to attain miniaturization and light weight thereby excluding the interference between signals. CONSTITUTION:A microwave signal given to an input terminal 1 is divided into two by a directional coupler 20a. The one signal is given to an amplifier 5 on one side and the other signal is given to an amplifier 6 on the other side. The signal outputted from the amplifiers 5, 6 is given to a directional coupler 20b and the signals are synthesized and outputted at an output terminal 2. The two amplifiers 5, 6 are provided to two dielectric bases via a ground conductor 12 inbetween to halve the entire size thereby attaining miniaturization and light weight. Moreover, the interference between the signals is excluded without ridge coupling by the coupling conductor. Thus, the input signal is processed with excellent electric characteristic.
