ACMD-6125
Band 25 Duplexer
Data Sheet
Description
The Avago ACMD-6125 is a highly miniaturized duplexer
designed for use in Band 25 (1850.25 – 1914.75 MHz UL,
1930.25 – 1994.75 MHz DL) handsets and mobile data ter-
minals.
Low Insertion Loss in the Tx channel minimizes current
drain from the power amplifier, while low Rx channel In-
sertion Loss improves receiver sensitivity.
The ACMD-6125 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-6125 is designed with Avago Technologies’ in-
novative Film Bulk Acoustic Resonator (FBAR) technology,
which makes possible ultra-small, high-Q filters at a frac-
tion of their usual size. The excellent power handling ca-
pability of FBAR bulk-mode resonators supports the high
output power levels used in mobile communications ap-
plications, while adding virtually no distortion.
The ACMD-6125 also utilizes Avago’s advanced Microcap
bonded-wafer, chip scale packaging technology. This pro-
cess allows the filters to be assembled into a molded chip-
on-board module with an overall size of only 1.6 x 2.0 mm
and height of 0.9 mm. The ACMD-6125 is compatible with
standard 1.6 x 2.0 mm duplexer PCB footprints.
