Re: [Amps] HV MOSFETs for RF

For the last two weeks, I've been testing the new ANAN 8000DLE.  Worst-case IMD 
at 200W is -75 dBc and close to -80 dBc on some bands.  The PSDR mRx result was 
cross-checked with an Agilent N1996A spectrum analyzer.  The combination of 
LDMOS, adaptive pre-distortion and a highly-isolated RF sample path back to the 
receiver's sampling input all contribute to this extraordinary level of 
transmitted IMD performance.
