ACMD-7614
UMTS Band 1 Duplexer
Data Sheet
Description
The Avago ACMD-7614 is a highly miniaturized duplexer
designed for use in UMTS Band 1 (1920 – 1980 MHz UL, 2110
– 2170 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-7614 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-7614 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-7614 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
maximum size of 2.0 x 2.5 mm and maximum height of
0.95 mm. The ACMD-7614 is compatible with standard 2.0
x 2.5 mm duplexer PCB footprints.
