PROBLEM TO BE SOLVED: To provide a microwave circuit with a plurality of degrees of coupling in the case of delivering part of signal power delivered through one transmission line to other transmission line depending on its degree of coupling. SOLUTION: Each input terminal of switches 15, 17 is connected to both ends of a 3rd transmission line 13 placed between 1st and 2nd transmission lines 11, 12 and one of output terminals of the respective switches is connected via resistors 16, 18 to ground and the other of the output terminals is connected directly to ground.
