SWITCHING CIRCUITS FOR BRIDGE COMBINERS

Abstract:

A switching circuit can be provided for a coupling circuit having a common node and configured to couple the common node to a first group of filters through a first path and to couple the common node to a second group of one or more filters through a second path. The coupling circuit can be further configured such that an impedance provided by each filter of the first group for a signal in each band of the second group results in the signal being sufficiently excluded from the first path, and such that an impedance provided by each filter of the second group for a signal in each band of the first group results in the signal being sufficiently excluded from the second path. The switching circuit can be configured to provide a filter selection functionality along either or both of the first and second paths.
