  • Electronically configurable transmit and receive paths for FDD wireless communication devices
    Patent number: 7587177
    Abstract: Methods and systems are provided for allowing an FDD radio to be configured to operate in Rx-high/Tx-low or Rx-low/Tx-high modes of operation. In accordance with one aspect, this is achieved in an FDD radio configuration that includes multiple switches, multiple Rx electronics, and multiple Tx electronics, allowing a diplexing filter to have selectively coupled to its high and low terminals desired Tx or Rx paths, such as to allow the radio to operate in one or another mode.
