This page will explain the simple technique devised by Dr. Steve Cripps, for predicting output power of microwave amplifiers based on load-line analysis. The so-called Cripps technique has substituted for large-signal models and load pull data quite successfully. Sometimes the simplest ideas are the best ideas, and this is a case in point.

Dr. Cripps has two books on microwave power amplifiers that you can find in any reputable engineering library:

RF Power Amplifiers for Wireless Communications

Advanced Techniques in RF Power Amplifier Design

Cripps first published his idea in 1983 in A theory for the prediction of GaAs FET load-pull power contours,†in the IEEE MTT Symposium Digest.

Here's a photo of Dr. Cripps receiving a "best paper" award in 2003... probably not his first, nor his last. You can read his resume here.

More to come!
