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.
