Abstract
A transceiver includes a radio-frequency (RF) front-end circuit, a dedicated RF front-end circuit, and a switchable matching circuit. The RF front-end circuit deals with communications of at least a first wireless communication standard. The dedicated RF front-end circuit deals with communications of a second wireless communication standard only. The switchable matching circuit is coupled to the RF front-end circuit, the dedicated RF front-end circuit, and a signal port of a chip. The switchable matching circuit provides impedance matching between the signal port and the RF front-end circuit when the RF front-end circuit is in operation, and provides impedance matching between the signal port and the dedicated RF front-end circuit when the dedicated RF front-end circuit is in operation. The RF front-end circuit, the dedicated RF front-end circuit, and the switchable matching circuit are integrated in the chip.
