I am designing linear power amplifier for cell phone, all of our PAs (L/M/HB) need 2nd harmonic termination to get good linearity and PAE. Removing the 2nd harmonic termination degrades performance a lot no matter how we tune it. However I know that removing the harmonic termination while maintaining the performance is possible. Does anyone here knows the trick?
