RF Amplifiers : 3040 Products

Power Amplifier (PA) is the core component of the RF front end, which converts the Power of the Power supply to the current changing according to the input signal by the current controlling effect of the triode or the voltage controlling effect of the field effect tube. PA is mainly used for transmitting links. By amplifying the weak radio frequency signal in the transmitting channel, the signal can successfully obtain high enough power, so as to achieve higher communication quality, stronger battery life, and longer communication distance. PA performance can directly determine the stability and strength of communication signals.
