PDF RF Power Amplifiers for Wireless Communications Circuit Diagram With a well-designed RF amplifier, wireless communication systems can benefit from enhanced signal strength, improved signal quality, and extended transmission range. Frequently Asked Questions (FAQ) 1. What is the purpose of an RF amplifier? An RF amplifier is designed to increase the power of a radio frequency (RF) signal. Power amplifier is the main power consumption block in any advanced wireless communications system. When the DC power is limited, it is crucial to design power amplifiers with high power-added efficiency. The output power and efficiency depends on the active device, bias conditions according to the operating class, matching networks, and so on.
