Abstract
A transceiver includes: a first transforming network arranged for using a first input impedance to receive a first modulated signal and using a first output impedance to output a first transformed signal during a transmitting mode of a first communication standard, and for using the first input impedance to receive a second modulated signal and using a second output impedance to output a second transformed signal during the transmitting mode of a second communication standard; a second transforming network arranged for using a second input impedance to receive the second transformed signal and using a third output impedance to output a first RF signal to a connecting port of the transceiver during the transmitting mode of the second communication standard; a power amplifier, arranged to generate a second RF signal; and a switching circuit for selectively coupling the second transformed signal to the second transforming network.
