ACMD-4102
UMTS/NCDMA/Co-band GSM Rx Band 2 Duplexer
with Balanced Rx Port
Data Sheet
Description
The Avago ACMD-4102 is a highly miniaturized duplexer
designed for use in UMTS and NCDMA Band 2 (1850.48 –
1909.52 MHz UL, 1930.48 – 1989.52 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-4102 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-4102 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-4102 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 1.05 mm.
The ACMD-4102 is compatible with standard 2.0 x 2.5 mm
duplexer PCB footprints.
