... In this PCB layout the grounding loops are minimised to realise good ultimate rejection. Optimised PCB layout for SAW filters in QCC8C package, pinning 2,5 (top side, scale 1:1) The bottom side is a copper plane (system ground area). The input and output grounding pins are isolated and connected to the common ground by separated via holes ...
