摘要：
A switching circuit for use in a frequency division duplex (FDD) spectrum re-allocated for time division duplex (TDD) applications comprises a first filter configured to filter a TDD receive signal, a duplex filter configured to filter an FDD receive signal, and a plurality of switches configured to route the FDD receive signal from an antenna through the duplex filter to receiver circuitry and to route the TDD receive signal from the antenna through the first filter to the receiver circuitry such that the FDD and TDD receive signals share the FDD spectrum.
