Hi all,
I am looking into using linear RF power amplifiers within a marine VHF radio application. I have limited experience with linear RF PAs, and was wondering;
What processes/tests/benchmarks can I use to characterise the linearity of an RF PA?
Ideally, something I can use to make apples-to-apples comparisons between different RF PA options, as well as determining how the linearity changes over my input power range. I do not have access to a network vector analyser, but I do have signal generators and spectrum analysers available for testing.
Thanks in advance.
