Mounting Information
PCB ground pattern length and width can be 0.002-0.003 inches larger than filter footprint.
Dimensions of filter launch and PCB launch pattern should be closely matched.
It is suggested that PCB ground metal be pulled back from RF I/O trace to account for component
alignment tolerance. Ground via depth and spacing should be set so as not to create any
resonances at the frequency of operation.
Reference SMT Filter Mounting application note for additional mounting information.
