question about PA's load-pull matching
Oct 26^th, 2006, 7:17pm

Hi,all
I am a graduate major in RF PA design. I used the cadence spectreRF to sim load-pull matching. I followed the user guide to matching the output of PA. I just wonder how to check the results of my matching if it is correct.

Just like the conjugate matching, when it is well matched that S22 should below -12dB. I wonder if there is a standard like the conjugate matching to check the load-pull matching.

Does anyone can give me some advice?

Thanks a lot!

If you meet/optimise your specs, then the load pull matching is complete.
