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 boards are available for sampling. (See board draw-

ing in Figures 7, 8, and 9.)

• 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.
