Agilent 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 perfor-
mance 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 compo-
nents, eliminating switch loss,
and reducing programming
complexity.
In typical cellular phone archi-
tectures, 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 sensi-
tivity. High rejection keeps
unwanted signals out of the
receive path.
Agilent's thin-Film Bulk Acoustic
Resonator (FBAR) technology
makes possible high-Q filters at a
fraction of their usual size.

Notes:
1. Temperature is defined at case T
C
, the
temperature of the underside of the filter
where it makes contact with the circuit board.
2. Specifications are guaranteed over the given
temperature range. Operation in excess of
any one of these conditions may result in
permanent damage to the device.

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 5)
Demo board uses 10 mil top,
18 mil bottom Greek Coplanar
Waveguide Over Ground plane
(CPWG) style board. (See
board layer Figure 5, 6)
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-Signal-
Ground (GSG) type board is
used, better return loss can be
achieved since it eliminates
connector mismatch.
Demo Boards
SMA connectorized Demo boards
are available for sampling. (See
board drawing in Figure 5).
