ACPF-7001
High Rejection Tx Filter for US PCS Band
Data Sheet
Description
This product is a high rejection full band transmit
filter designed for US PCS handsets. Its performance
rivals splitband surface acoustic wave (SAW) transmit filters. Since the rejection is provided by a single
filter, no switches are required, saving board space
and external components, eliminating switch loss,
and reducing programming complexity.
In typical cellular phone architectures, the transmit
filter fits between the driver amplifier and the
power amplifier. This filter reduces the noise in the
Rx band being amplified by the transmit chain,
enhancing receiver sensitivity. High rejection keeps
unwanted signals out of the receive path.
Avago’s thin-Film Bulk Acoustic Resonator (FBAR)
technology makes possible high-Q filters at a
fraction of their usual size.

PCB Interface and
Mounting Instructions
Mounting Consideration and
Board Description
The ACPF-7001 filter has one
input (Pin 4), one output (Pin 8)
and 6 grounds (Pins 1, 2, 3, 5, 6,
7). Furthermore, the inside of the
filter (center pad Pin 9) is
ground-plane; therefore it must
be soldered to PCB ground.
In summary:
• Pins 1, 2, 3, 5, 6, 7, 9 are
grounded. (Figure 6)
• Demo board uses 10 mil top,
18 mil bottom Greek Coplanar
Waveguide Over Ground plane
(CPWG) style board. (See
board layer Figure 6, 7)
Note: For best performance, try
to reproduce this board stack up
closely. The demoboard uses
CPWG transmission lines for high
isolation between two ports. It
uses via holes to connect the
CPWG line from the underside of
the board to the filter mounting
pads on top. If Ground-SignalGround (GSG) type board is
used, better return loss can be
achieved since it eliminates
connector mismatch.

mounting pads on top).
