Abstract

PURPOSE:To avoid lowering of the output and thus to enchance the reliability of the system by maintaining the input phase at 90 deg. for the 2nd directional coupler when the input of one side of the 1st directional coupler is stopped and thus grounding the switch un accordance with the output of the detector. CONSTITUTION:Branch path 9 the terminal of which is grounded or opened is provided at one side of the connecting transmission path of directional couplers 41 and 42, and grounding switches 71 and 72 are installed at the positions of the half wavelength and 3/4 wavelength from the terminal of the branch path. In addition, detectors 51 and 52 are installed to detect the presence or absence of the two input of coupler 41, and switches 71 and 72 are switched alternatively to the grounded state in response to the output of detectors 51 and 52 in order to maintain the input phase difference at 90 deg. for coupler 42 when the input of one of the two detectors is stopped. As a result, a large amount of reduction can be avoided for the output, thus enhancing the reliability of the system.
