Circuit with first and second terminals coupled together via a branch-interconnection arrangement

A circuit comprising:

• a common terminal and at least a first terminal and a second terminal, wherein the common terminal is coupled to a first circuit branch at a branch node and the first circuit branch terminates at the first terminal, and wherein the common terminal is coupled to a second circuit branch at the branch node and the second circuit branch terminates at the second terminal;
• wherein the first circuit branch includes a first quarter wavelength transmission line having a first end coupled to the branch node and a second end coupled to the first terminal;
• wherein the second circuit branch includes a second quarter wavelength transmission line having a first end coupled to the branch node and a second end coupled to the second terminal;
• wherein the first terminal and the second terminal are coupled together via a branch-interconnection arrangement comprising at least a resistor;
• wherein the circuit comprises:
• a first switched arrangement comprising a first switch having a first switch-terminal and a second switch-terminal, wherein the first switch-terminal is coupled to the common terminal, and wherein a first resistor and a first capacitor are arranged in parallel and coupled between the second switch-terminal and a reference terminal, the reference terminal configured to be coupled to a reference voltage;
• and
• a second switched arrangement comprising a second switch having a first switch-terminal and a second switch-terminal, wherein the first switch-terminal is coupled to the first terminal, and wherein a second resistor and a second capacitor are arranged in parallel and coupled between the second switch-terminal and the reference terminal, wherein the first quarter wavelength transmission line is coupled between the first switched arrangement and the second switched arrangement.
