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.
