Abstract
A transceiving system utilizing a shared filter module is provided. The shared filter module is selectively filtering signals in a first band in a first mode and a second band in a second mode. The first mode is a receiver mode whereas the second mode is a transmission mode. The shared filter module comprises a compound filter comprising two low pass filters and a coupling controller to manage input and output wiring of the low pass filters. When the coupling controller is enabled in the first mode, the compound filter acts as a bandpass filter. When the coupling controller is disabled, the compound filter acts as two independent low pass filters.
