Dear NXP engineers:

 

I designed a PCB board to evaluate the performance of MMZ25333BT1 based on the schematic shown in figure 3 of the attached datasheet. The output of my board is abnormal: there are some harmonics whose frequency is integer times of 1.2GHz even when no input is fed. In the attachment, I also included my PCB design file. Could somebody give me some hints about the issue?

 

PS: the PCB is designed using Altium Designer 18.0.11
