A few basic questions about Power Amplifier theory - RF Cafe Forums

Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views. It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if you would like to post something on RF Cafe's Facebook page, please do.

Below are all of the forum threads, including all the responses to the original posts.

I wold like to know whether Feedforward linearisation can be implemented without a variable gain and phaseshift mechanism.(completely in RF, without anydigital processing or microcontrollers).

As a general statement, whether or not you need adaptive circuitry for feedforward linearization depends on how stable (in a general sense, not "will it oscillate?") your design is. If parameters change with time, adaptivity is critical - because feedforward depends on cancellation of distortion products, delay and amplitude control is critical.

Good Luck!
