Abstract: A flexible power amplifier can be adapted during operation for use in connection with two or more different wireless standards. In at least one embodiment, adaptations to power transistor size, RF bias current, and matching are made when a corresponding multi-standard wireless device changes the wireless standard under which it is currently operating.

Abstract: In one embodiment a universal front end module for network communications is disclosed. The module can include a mode controller coupled to components of a transmission path. A first tunable filter on a transmit path can receive a mode control signal from the mode controller and receive a signal to be transmitted and provide a filtered output signal responsive to the mode control signal and the signal to be transmitted. The mode control signal can be associated with a predetermined network protocol such as WiMax, a WiFi, a 3G LTE and a cellular standard where each standard has a predetermined operating frequency and protocol. The module can also include a tunable power amplifier to provide an amplified transmittable signal over a single transmit path can be utilized to transmit the transmittable signal in at least two different modes responsive to the mode controller.
