Abstract
A power amplifier that can support multiple communication networks while maintaining power efficiency across each of the supported communication networks is disclosed. In some implementations described herein, a power amplifier module includes a bypass circuit that enables different voltage supplies to be provided to the power amplifier. By regulating the voltage supply provided to the power amplifier, the power amplifier can support different communication networks while maintaining power efficiency across a dynamic frequency range. Moreover, embodiments herein may include a buck converter, or other form of DC-DC converter, that enables the power amplifier to operate with respect to multiple communication networks. Advantageously, in certain embodiments, because wireless devices that include multiple power amplifiers often require a DC-DC converter to support at least some of the communication networks, the inclusion of the buck converter in the embodiments described herein does not add additional cost or size to the wireless device.
