ACFM-7103
PCS/Cellular/S-GPS Quintplexer
Data Sheet
Description
The Avago Technologies’ ACFM-7103 is a reduced size
quintplexer that combines PCS and Cellular duplexer
functions with a GPS filter. This device simplifies handset
applications that are designed for simultaneous voice
service and GPS positioning.
The ACFM-7103 features two antenna connections, one
for the duplexers and a separate antenna port for the GPS
filter. The ACFM-7103 can be used for single antenna ap-
plications by simply connecting both antenna terminals
together with a single, external SMT component.
The ACFM-7103 is designed with Avago Technologies’
Film Bulk Acoustic Resonator (FBAR) technology. The
ACFM-7103 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 4 x 7 mm and maximum
height of 1.2 mm.
Low Tx Insertion Loss reduces power amplifier current,
extending battery life and talk time. The ACFM-7103
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.

Notes:
1. Operation in excess of any one of these conditions may result in permanent damage to the device.
2. The device will function over the recommended range without degradation in reliability or permanent
change in performance, but is not guaranteed to meet electrical specifications.
3. TC is defined as case temperature, the temperature of the underside of the quintplexer where it makes
contact with the circuit board.
