Abstract
Official abstract text for this publication.
A combiner circuit can be implemented as a coupling circuit having a common node and configured to couple the common node to one of first and second groups of filters through a first path and to couple the common node to the other group through a second path. The coupling circuit can be further configured such that the impedance provided by each filter of the one of the first and second groups for a signal in each band of the other group results in the signal being sufficiently excluded from the first path.
First claim
Opening claim text (preview).
1 . A radio-frequency architecture comprising: a first group of plurality of filters each configured to support a band such that a first frequency range covers the respective plurality of bands; a second group of one or more filters each configured to support a band such that a second frequency range covers the respective one or more bands, each filter of one of the first and second groups configured to provide an impedance at or near a short circuit impedance for a signal in each band of the other group, each filter of the other group configured to provide an approximately open circuit impedance for a signal in each band of the one of the first and second groups; and a coupling circuit including a common node and configured to couple the common node to one of the first and second groups through a first path and to couple the common node to the other group through a second path, the coupling circuit further configured such that the impedance provided by each filter of the one of the first and second groups for the signal in each band of the other group results in the signal being sufficiently excluded from the first path. 2 - 23 .
