Abstract
Disclosed are systems, circuits and methods related to low-loss bypass of a radio-frequency (RF) filter or diplexer. In some embodiments, a switching network circuitry can include a first switch that has an input pole configured to receive a radio-frequency (RF) signal, a pass-through throw configured to be connectable to the input pole to allow routing of the RF signal to an RF component, and at least one dedicated bypass throw configured to be connectable to the input pole and at least one bypass conduction path. The switching network circuitry can further include a second switch that has a pole and a throw, and is connectable between an output of the RF component and the bypass conduction path. Use of the dedicated bypass throw(s) in the first switch allows implementation of low-loss bypass of the filter or diplexer.
