Hello, A customer of ours is using the MKW21D512VHA5 with a Texas Instruments CC2591 Power Amplifier. They have tried using the harmonic trap shown the reference design.  It definitely helped when transmitting but it adversely affected the receiving capability. Any thoughts on what to try to improve suppressing these harmonics?

 

Thanks!
