Similarly, in June 2021, Skyworks Solutions Inc. introduced RF power amplifiers designed for 5G applications, offering high linearity and efficiency.

An RF power amplifier (RF-PA) is a crucial component of many wireless transmitters. The pre-stage circuit of the transmitter's modulation oscillator circuit generates a weak RF signal that must pass through a buffer stage, an intermediate amplification stage, and a final power amplification stage to achieve sufficient RF power to be transmitted to the antenna.

RF power amplifiers are highly sensitive, with higher gain, enhancing their ability to boost weak signals received by the receiver. They improve selectivity, allowing for the differentiation of desired signals from a variety of incoming signals. By boosting weak incoming signals to a higher level, RF power amplifiers enhance the signal-to-noise ratio.
