Abstract: A reconfigurable circuit for differential network includes: first circuit which is a two-port differential circuit; first cross-coupled switch circuit connected to first port on one side of the first circuit in parallel; and second circuit connected to second port on the other side of the first cross-coupled switch circuit in series. The first cross-coupled switch circuit includes: first-series switch disposed between and connected to first terminal of the first port and first terminal of the second port in series; second-series switch disposed between and connected to second terminal of the first port and second terminal of the second port in series; first cross-coupled element disposed between and connected to the first terminal of the first port and the second terminal of the second port; and second cross-coupled element disposed between and connected to the second terminal of the first port and the first terminal of the second port.
