Surface Mount Lowpass Filter Series Description DLI introduces its new high frequency surface mountable catalog lowpass filters. These LPFs incorporate DLIs high dielectric ceramic materials which provide small size and minimal performance variation over temperature. The catalog LPFs are offered in a variety of frequency bands, which offers a drop in solution for high frequency attenuation.

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.
