Agilent ACPF-7002
High Rejection Tx Filter
for US PCS Band
Data Sheet
General Description
The ACPF-7002 is a high
rejection full band transmit
filter designed for US PCS
handsets. Its performance rivals
splitband surface acoustic wave
(SAW) transmit filters. Since a
single filter provides the
rejection, no switches are
required, saving board space
and external components,
eliminating switch loss, and
reducing programming
Features
• High rejection from a single filter
With no switches required.

The ACPF-7002 FBAR transmit
filter utilizes Agilent's Microcap
bonded-wafer chip scale
packaging technology. This
process allows the ultra small
filters to be assembled into a
Molded Chip on Board (MCOB)
module.

In typical cellular phone
architectures, the transmit filter
fits between the driver amplifier
and the Power Amplifier. The
ACPF-7002 FBAR 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.
Applications
• US PCS band handsets
• Wireless Data terminals
Agilent’s thin-Film Bulk
Acoustic Resonator (FBAR)
technology makes possible high-
Q filters at a fraction their
