Abstract
A transceiver includes: a radio-frequency (RF) front-end circuit; a dedicated RF front-end circuit; and a switchable matching circuit, integrated in a chip. The RF front-end circuit deals with communications of a first wireless standard, and the dedicated RF front-end circuit deals with communications of a second wireless standard. 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, and includes: a first capacitive circuit coupled to the signal port; a first switch circuit coupled between the first capacitive circuit and the dedicated RF front-end circuit; a second capacitive circuit coupled to the dedicated RF front-end circuit; and a second switch circuit coupled to a second terminal of the second capacitive circuit.
