PCB Interface & Mounting instructions
Mounting Consideration and board description
The ACPF-7003 FBAR filter 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 filter 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.
