Hi!
Could you, please tell me, what i'm doing wrong?
There are graphs of HD2 and HD3 in the datasheet of ths3217 t. It's easy to see, that if a signal has amplitude about 2,5 V in the output of ths3217, there will be about -50 dBc HD3 at 60 MHz on 100 Ohm load. Simulation result is more worse: only about -42 dBc with output signal amplitude 0 dBV (1V amplitude).
