We are revising a design using the NRF9E5, we are experiencing problems with the third harmonic when configured for 915MHz band, the higher we go up the band the worse the problem becomes.
We are using a SAW filter in the design.
After reviewing competitors literature we are proposing to implement a third order harmonic filter. Do you have any experience of this or do you have a reference design for a suitable filter?
many thanks
