With so much attention on IBOC, it is appropriate to step back and review the basic principles of RF amplifiers. The radio transmitter is a collection of stages. Each stage modifies the signal in some ...

What are TDA IC’s? TDA integrated circuits series are very well appreciated and used in amplifier designs and projects. TDA audio amplifier circuits are produced in generally by Philips and ...

Despite recent improvements in the performance of RF LDMOS field-effect transistors (FETs), temperature drift and aging continue to affect the efficiency and linearization of power amplifiers using ...

Blame it on RF power amplifiers. Large and costly, they comprise roughly 40% of a basestation's cost. And since these amplifiers must transmit wide bandwidth signals of various modulation types, ...
