IMD3. "
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.
