Abstract
A circuit arrangement includes an antenna port, a transmission port, and a reception port, each of which is connected to one respective 90° hybrid that splits an input signal into two output signals that are in quadrature. The circuit arrangement also includes two duplexers which are connected in such a way that the two output signals emitted by the 90° hybrid that is connected to the transmission port constructively interfere on the antenna port, while spurious signals caused by the two output signals destructively interfere on the reception port.
