摘要： A power amplifier (PA) line-up (210) and a method (500) for more efficiently utilizing battery power are disclosed. PA line-up (210) includes a driver (220), a matching circuit (214), and a PA (230) coupled to a matching circuit (216), wherein matching circuit (216) is configured to be coupled to a filter (260). PA line-up (210) includes a transmission line (260) coupled to matching circuit (216) and a switch (262) configured to selectively couple driver (220) to either matching circuit (214) or matching circuit (216) such that signal (205) is capable of by-passing PA (230) when signal (205) does not need to be amplified by PA (230). Furthermore, PA line-up (210) may include a second transmission line (250) so that signal (205) is capable of by-passing a driver (220) and a PA (230) when signal (205) does not need to be amplified by driver (220) and PA (230).

摘要： A transceiver includes a harmonic termination circuit that receives a tunable harmonic voltage from a power amplifier control. The harmonic termination circuit includes a variable capacitor that is capable of adjusting its capacitance in response to the tunable harmonic termination voltage to achieve at least two modes of operation. The at least two modes of operation may be EDGE mode and GSM mode. In this embodiment, the harmonic termination circuit allows for linearity specifications of EDGE to be met, while not degrading the efficiency of the transceiver when operating in GSM mode. In one embodiment, the harmonic termination circuit further includes an inductive element in series with the variable capacitor.
