摘要： PURPOSE: A variable differential attenuator using phase is provided to control an amplitude and phase of transmitted and received signals at the same time using a phase difference of a phase controller, thereby removing interference in the transmitted and received signals. CONSTITUTION: A power distributor(41) distributes the transmitted and received signals to have the same phase and amplitude. A phase controller(43) varies the phase of the signal from the power distributor(41) via a line for transferring a signal. A power mixer(42) mixes the signals applied from the power distributor(41) and A phase controller(43). The attenuator enables the variation of a phase from 0°C to 360°C and has an attenuation characteristic such that the phase variation is repeated by each 2&phgr;. The attenuator varies a certain phase of a signal by 180 degree under the same frequency of the signal.
