ACMD-7411
UMTS Band 2 Duplexer with
Balanced Rx Port
Product Brief
Description
The Avago ACMD-7411 is a highly miniaturized duplexer
designed for use in UMTS Band 2 (1850 MHz to 1909 MHz UL,
1930 MHz to 1989 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 Rx port is balanced to
preserve CMR and simplify the interface to baseband chipsets.
The ACMD-7411 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-7411 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-7411 also uses 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 1.6 mm ×
2.0 mm and height of 0.9 mm. The ACMD-7411 is compatible
with standard 1.6 mm × 2.0 mm duplexer PCB footprints.
