ACMD-4102
UMTS/NCDMA/Co-band GSM Rx Band 2 Duplexer
with Balanced Rx Port
Data Sheet
Description
Features
The Avago ACMD-4102 is a highly miniaturized duplexer Miniature Size
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.
– 2.0 x 2.5 mm size
– 1.05 mm Max Height
– Standard 2 x 2.5 mm PCB footprint
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
Balanced Rx Port, 150
High Isolation enables elimination of interstage filter
is balanced to preserve CMR and simplify the interface to Co-banding enables elimination of the GSM Rx filter
baseband chipsets.
High Power Rating
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.
– 33 dBm Abs Max Tx Power
Environmental
– RoHS 6 Compliant
– Halogen free
– TBBPA Free
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.
Specifications
Rx Band Performance, -20 to +85° C
– Insertion Loss (UMTS): 3.6 dB Max
– Rx Noise Blocking: 50 dB Min
Tx Band Performance, -20 to +85° C
– Insertion Loss (UMTS): 2.8 dB Max
– Tx Interferer Blocking: 55 dB Min
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.
Applications
UMTS and NCDMA handsets or data terminals operating
in the Band 2 frequency range.
