ACPF-7005
PCS (A-G) / UMTS Band 2 Tx Bandpass Filter
Data Sheet
Description
The Avago ACPF-7005 is a miniaturized Bandpass Filter
designed for use in handsets and mobile data terminals
operating in the PCS (Blocks A-G)/UMTS Band 2 Tx fre-
quency range (1850.6 – 1914.4 MHz).
In typical cellular phone architectures, this transmit filter
is placed between the driver amplifier and the power
amplifier. The high out-of-band rejection of the ACPF-7005
enhances receiver sensitivity by reducing noise in the Rx
band which would otherwise be amplified by the transmit
chain. The high rejection feature keeps unwanted signals
out of the receive path.
The Avago ACPF-7005 rivals split-band surface acoustic
wave (SAW) transmit filters. As a high rejection, single filter
solution, the ACPF-7005 eliminates the need for switching.
This saves board space and external components, while
eliminating switch loss and reducing programming
complexity.
The ACPF-7005 is designed with Avago Technologies’ in-
novative Film Bulk Acoustic Resonator (FBAR) technology,
which makes possible ultra-small, high-Q filters at a
fraction of their usual size. The excellent power handling
capability of FBAR bulk-mode resonators supports the
high output power levels used in mobile communications
applications, while adding virtually no distortion.
The ACPF-7005 also utilizes Avago Technologies’ advanced
Microcap bonded-wafer, chip scale packaging tech-
nology. This process allows this filters to be assembled
into a molded chip-on-board module with an overall size
of only 1.6 x 2.0 mm and maximum height of 1.1 mm.
