PCS/Cellular/GPS Quintplexer
Datasheet
Description
The Avago Technologies’ ACFM-7101 is a quintplexer that
combines PCS and Cellular duplexer functions with a GPS
filter, thereby eliminating the need for antenna switching
between services.
The ACFM-7101 is designed with Avago Technologies’ Film
Bulk Acoustic Resonator (FBAR) technology. The ACFM-7101
also utilizes Avago Technologies’ innovative Microcap bonded-
wafer, chip scale packaging technology. This process allows
the filters to be assembled in a module that is less than 1.3 mm
high with a footprint of only 5 mm x 8 mm.
Low Tx Insertion Loss reduces power amplifier current,
extending battery life and talk time. The ACFM-7101
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 Technologies’
FBAR bulk-mode resonators supports the high Tx output power
levels needed in handsets while adding virtually no distortion
