What are Power Amplifiers?

During the processing of signals in wireless devices, many components exhibit loss. To ensure that there is sufficient power in the device, power amplifiers are responsible for amplifying the signals to the right power level after taking the data from the base band and transceiver ICs and then sending the signals over the air to the base station.
