ACMD-7617
UMTS Band 1 Duplexer
Data Sheet
Description
The Avago ACMD-7617 is a highly miniaturized duplexer
designed for use in Digital Enhanced Cordless Telecom-
munications (DECT) applications operating in UMTS
Band 1 (1920 – 1980 MHz UL, 2110 – 2170 MHz DL).
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-7617 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-7617 is designed with Avago Technologies’
innovative Film Bulk Acoustic Resonator (FBAR) technol-
ogy, 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-7617 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 2.0 x 2.5 mm and maximum height of 0.95 mm.
The ACMD-7617 is compatible with standard 2.0 x 2.5 mm
duplexer PCB footprints.
