DIVERSITY RECEIVER FRONT END SYSTEM WITH PHASE-SHIFTING COMPONENTS

摘要

Diversity receiver front end system with phase-shifting components. A receiving system can include a controller configured to selectively activate one or more of a plurality of paths between an input of the receiving system and an output of the receiving system. The receiving system can further include a plurality of amplifiers, each one of the plurality of amplifiers disposed along a corresponding one of the plurality of paths and configured to amplify a signal received at the amplifier. The receiving system can further include a plurality of phase-shift components, each one of the plurality of phase-shift components disposed along a corresponding one of the plurality of paths and configured to phase-shift a signal passing through the phase-shift component.

1. A receiving system comprising:
a controller configured to selectively activate one or more of a plurality of paths between an input of the receiving system and an output of the receiving system; a plurality of amplifiers, each one of the plurality of amplifiers disposed along a corresponding one of the plurality of paths and configured to amplify a signal received at the amplifier; and a plurality of phase-shift components, each one of the plurality of phase-shift components disposed along a corresponding one of the plurality of paths and configured to phase-shift a signal passing through the phase-shift component, the plurality of phase-shift components including a first phase-shift component disposed along a first path of the plurality of paths corresponding to a first frequency band and configured to phase-shift a second frequency band of a signal passing through the first phase-shift component such that a second initial signal propagated along a second path of the plurality of paths corresponding to the second frequency band and a second reflected signal propagated along the first path are at least partially in-phase.
