Understanding the Basics of Low-Noise and Power Amplifiers in Wireless Designs

Two radially different forms of amplifier interface with an antenna in any wireless system where both transmitter and receiver are present. The receiver amplifier must have low noise , high dynamic range, good intercept point and the like. The Power amplifier for the transmitter must be able to provide power to the antenna in the most efficient manner. here efficiency, power match and other issues are key. Find out all you need to know about these two forms of amplifier in this useful article.
