摘要
A ring-filter switch is suggested for a low loss wideband filter with on-state and very sharp bandstop filter with off-state. It consists of a ring filter and a switching diode. The ring filter is a wideband filter but a band-stop filter with a certain condition. The fact can be used as a switch. To verify it, a microstrip ring-filter switch is fabricated and measured at a center frequency of 3 GHz.
