摘要： 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.

摘要： Provided herein are methods of reconfiguring directional couplers in an RF transceiver. The methods can include designing and reconfiguring the directional couplers to provide high directivity and a desired coupling factor using configurable capacitors to effect a mutual coupling and using lumped components or delay lines to effect a phase shift. The reconfigurable directional couplers can be designed for multi-band operation with an adjustable coupling factor conducive to semiconductor process integration. The reconfigurable directional couplers can have variable phase shifters to achieve a desired level of directivity in the coupler. In various examples, the methods include monitoring the frequency of power signals received by the reconfigurable directional couplers, and adjusting the configurable capacitors and/or variable phase shifters to maintain desired directivity and coupling factors over multi-band operation of the reconfigurable directional couplers.
