Quick Poll: What’s Your Go-To RF PA Topology?

March 21, 2024
Out of these 10 most common RF amplifier classes, which is your default style?

Check out other Microwaves & RF Quick Polls.

The last thing a signal sees before reaching an antenna to be radiated out into free space is an RF power amplifier (PA). That signal made its way through various other components and circuits such as low-noise amplifiers (LNAs), mixers, and other signal-processing elements. But it’s the RF PA that will punch the signal up to the level it needs to ensure reliable communication.

There’s a few basic amplifier classes as well as several advanced RF PA types to select from when you’re designing the final stages of a transmitter. Tell us which one you use most often, and feel free to expound on why in the comments below.
