Gallium nitride (GaN) RF transistors have traditionally been depletion mode, making them difficult to bias. High frequency enhancement mode transistors, such as the EPC8000 series eGaN FETs from EPC, ...

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 ...

If you didn’t know better, you might think the phrase “class A amplifier” was a marketing term to help sell amplifiers. But it is, of course, actually a technical description of an amplifier that ...

When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. If you have read an amplifier review or looked at the specifications for an amp, the chances are ...

An RF power amplifier is a device designed to convert a low power radio frequency signal into a higher power radio frequency signal. Moreover, based on several parameters RF power amplifiers are ...

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, ...
