ACFM-7109
PCS/Cellular Band Quadplexer
Data Sheet
Description
The Avago Technologies’ ACFM-7109 is a quadplexer
that combines PCS and Cellular duplexers into a single,
miniature package.
The ACFM-7109 features a single antenna connection,
eliminating the need for antenna switching. All ports are
matched to 50 ohms.
The ACFM-7109 is designed with Avago Technologies’
Film Bulk Acoustic Resonator (FBAR) technology. The
ACFM-7109 also utilizes Avago Technologies’ innovative
Microcap bonded-wafer, chip scale packaging technol-
ogy. This process allows the filters to be assembled in a
module with a footprint of only 3 x 5 mm and maximum
height of 1.05 mm.
Low Tx Insertion Loss of the ACFM-7109 reduces power
amplifier current, extending battery life and talk time. The
ACFM-7109 enhances receiver sensitivity and dynamic
range with low Rx Insertion Loss and high rejection of Tx
signals at the Rx ports.
The excellent power handling capability of Avago Tech-
nologies’ FBAR bulk-mode resonators supports the high
Tx output power levels needed in handsets while adding
virtually no distortion
