Circuit

A circuit includes a common terminal, a first terminal, and a second terminal, wherein the common terminal is coupled to first and second circuit branches at a branch node; wherein the first/second circuit branch comprises a respective first/second quarter wavelength transmission line having a first end coupled to the branch node and a second end coupled to the first/second end, respectively; wherein the first and second ends are coupled together via a branch interconnect arrangement; wherein the circuit comprises: a first switch arrangement comprising a first switch having first and second switch terminals, where the first switch terminal is coupled to the common terminal, and where a first resistor and a first capacitor are arranged in parallel and coupled between the second switch terminal and a reference terminal; and a second switch arrangement coupled to the first end, where the first quarter wavelength transmission line is coupled between the first switch arrangement and the second switch arrangement.
