Disclosed is a microwave circuit suitable made into a monolithic microwave integrated circuit (MMIC). This microwave circuit includes a main line comprising a distributed constant line formed on a major surface of a substrate, and a stub connected in parallel with the main line in which lines the characteristics admittance varies discontinuously. Because of the discontinuous variation of the characteristic admittance of the stub, the phase of the characteristic admittance is changed, so that the stub length can be reduced.
