ACMD-7605
Miniature UMTS Band 8 Duplexer
Data Sheet
Description
The Avago Technologies’ ACMD-7605 is a miniature
duplexer designed for use in UMTS Band 8 (880 – 915
MHz UL, 925 – 960 MHz DL) handsets and mobile data
terminals.
The ACMD-7605 enhances the sensit­ ivity and dynamic
range of handset receivers by providing more than 51 dB
attenuation of the transmitted signal at the receiver input
and more than 48 dB rejection of transmit-generated
noise in the receive band.
Maximum Insertion Loss in the Tx channel is only 3.5 dB,
which minimizes current drain from the power amplifier.
Insertion Loss in the Rx channel is a maximum of 4.0 dB,
thus improving receiver sensitivity.
The ACMD-7605 is designed with Avago Technologies’
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
the FBAR bulk-mode resonators supports the high output
power levels needed in handsets while adding virtually no
distortion.
The ACMD-7605 also utilizes Avago Technologies’ innova-
tive Microcap bonded-wafer, chip scale packaging tech-
nology. This process allows the filters to be assembled in
a molded chip-on-board module that is less than 1.2 mm
high with a maximum footprint of only 3.0 mm x 3.0 mm.
