Microwave bridge circuit for separating transmitted signal from received signal

The invention relates to a microwave bridge circuit for separating a transmitted signal from a received signal, comprising a circuit having: two electrical conductors connected in parallel; a first connection point on which the transmit signal is separated onto the first and second electrical conductors; a first electrical conductor having an attenuator for attenuating the separated first transmit signal; a second electrical conductor connected to the resonator, at a second connection point at which a separated second transmission signal is separated and the second electrical conductor is divided into two sections, the first section extending from the first connection point to the second connection point and the second section extending from the second connection point to a third connection point and transmitting the transmission signal retained at the second connection point, the length of each segment of the second electrical conductor corresponds to an integer multiple of an odd number of a quarter of the
