DIVERSITY RECEIVER FRONT END SYSTEM WITH SWITCHING NETWORK

摘要

Diversity receiver front end system with switching network. A receiving system can include a plurality of amplifiers, each one of the plurality of amplifiers disposed along a corresponding one of a plurality of paths between an input of the receiving system and an output of the receiving system and configured to amplify a signal received at the amplifier. The receiving system can further include a switching network including one or more single-pole/single-throw switches, each one of the switches coupling two of the plurality of paths. The receiving system can further include a controller configured to receive a band select signal and, based on the band select signal, enable one of the plurality of amplifiers and control the switching network.

1. A receiving system comprising:
a first amplifier disposed along first path between an input of the receiving system and an output of the receiving system and configured to amplify a signal received at the first amplifier; a second amplifier disposed along a second path between the input of the receiving system and the output of the receiving system and configured to amplify a signal received at the second amplifier; a single-pole/single-throw (SPST) switch disposed between the first path and the second path and configured to couple the first path and the second path; and a controller configured to receive a band select signal and, based on the band select signal, enable one of the first amplifier or the second amplifier and control the SPST switch.
