Part Number: LMH6401

dear

At 1Ghz, the performance of HD3 is only -58dbc. is it due to the filter performance of the front end? Or is there something wrong with layout?

any advise ，thanks in andance

Many things can influence the measured HD performance, a schematic would be necessary (loading is needed in particular)

Hello Raymond,

Also, if you can provide your measurement setup and a snippet/image of the PCB, those would help a lot too.

Thank you,
Sima
