Abstract

A laminated lowpass filter (100) is disclosed. The filter (100) has: a stack of dielectric substrates (301-312) having a ground via (209); a pi network coupled between an input (202) and an output (202'); and the ground via (209) is conductively filled and extends substantially through the sheets of dielectric (301-312) connecting a first ground plane (102) to a second ground plane (104) and is spaced a predetermined distance between a first and a second leg of the pi network, to define an isolation barrier that substantially minimizes the passage of stray signals therebetween.
