Hello Rmrusoti,

Is your PCB close to 71mm by 33mm? Have you adjusted the initial matching components up or down one value?  It doesn't seem to be off by much so adjusting the shunt 1.8pF capacitor or the 1.8nH series inductor up or down one value may be enough to recenter the band.

If you are still having trouble getting the band centered please contact to send them your S1P file to analyze.

Best regards,

Geoff S.
