ACMD-6225
Band 25 Duplexer
Product Brief
Description
The Avago ACMD-6225 is a highly miniaturized duplexer
designed for use in Band 25 (1850.25 MHz to 1914.75 MHz UL,
1930.25 MHz to 1995.75 MHz DL) handsets and mobile data
terminals.
Low insertion loss in the Tx channel minimizes current drain
from the power amplifier, while low Rx channel insertion loss
improves receiver sensitivity.
The ACMD-6225 enhances the sensitivity and dynamic range of
handset receivers by providing high isolation of the
transmitted signal from the receiver input and high rejection of
transmit-generated noise in the receive band.
The ACMD-6225 is designed with Avago Technologies'
innovative 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 ACMD-6225 also utilizes Avago Technologies' advanced
Microcap bonded-wafer, chip scale packaging technology. This
process allows the filters to be assembled into a molded
chip-on-board module with an overall size of only 1.4 x 1.8 mm
and height of 0.80 mm. The ACMD-6225 is compatible with
standard 1.4 x 1.8 mm duplexer PCB footprints
Applications
Smartphones, tablets, data terminals, and other
mobile/portable communication devices operating in the
Band 25 frequency range.
