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
complexity.
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.
Agilent’s thin- Film Bulk
Acoustic Resonator (FBAR)
technology makes possible high-
Q filters at a fraction their
usual size.
