Why Do RF Power Amplifiers Fail Outside the Lab?

Engineer's Law #1: The harsher the environment, the more likely the “perfect”amplifier suddenly becomes imperfect.

An RFPA that performs flawlessly in the lab may behave very differently inside a hot cabinet, on an outdoor platform, or aboard a vibrating vehicle.

 

That’s why environmental considerations should be part of the selection process from day one.

 

In this poster, we share some of the key environmental factors engineers should consider when selecting an RF power amplifier, including an environmental selection flow and our application-based selection guide. We hope it serves as a useful reference for engineers when making RFPA selection decisions.
