Patent ID: 7515016

Claim:
A method of impedance matching in a circuit including a power amplifier having a first impedance, the power amplifier being configured to provide a signal to a transceiver circuit having a second impedance that is higher than the first impedance, the transceiver circuit being capable of operating in a plurality of frequency bands, the method comprising: providing an analog circuit to substantially match the first impedance to the second impedance, the analog circuit comprising: a reconfigurable circuit that operates in a plurality of modes corresponding to the plurality of frequency bands used by the transceiver circuit, the reconfigurable circuit having a third impedance higher than the first impedance and the second impedance; a first impedance matching circuit coupled between the power amplifier and the reconfigurable circuit for matching the first impedance to the third impedance; and a second impedance matching circuit coupled between the reconfigurable circuit and the transceiver circuit for matching the third impedance to the second impedance.
