The new standard in IMD....

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.

Making everyone else look bad!

Yeah, I agree.

That was in reply to me posting about K1JJ and his 8877/4cx350 chain and it's - 55 db imd.  A couple folks had brought up that is probably the best you can hope for, using 'modern' equipment and not going to predistortion.

Will be interesting to see what a 3cx3k or 8877 pair would do wrapped into that system.  And at 200 watts, you can actually drive a 3000!
