pcb interface & mounting instructions mounting consideration and board description the acpf-7003 fbar flter has one input (pin 1), one output (pin 3) and two grounds (pins 2 and 4.) ? demo board uses 3 mil getek microstrip. the demo board uses cpwg transmission lines for high isolation between the two ports. it uses via holes to con - nect the cpwg line from the underside of the board to the flter mounting pads on top. note : for best performance, try to reproduce this board stack up closely. if ground-signal-ground (gsg) type board is used, better return loss can be achieved since it eliminates connector mismatch. figure 7. board stack up description figure 9. closer look at the recommended board footprint and soldermask figure 8. pcb footprint pad mils layer (ground) layer (signal) getek ml00d ( t =.9) 8 mils 0. mils getek ml00d ( t =.) layer1 (signal) getek ? material ml00d and rg00d getek ? ml00d ( =.9) getek ? ml00d ( =.) 0. mils demo boards demo boards are available for sampling.
