ACFM-7104
Quintplexer for PCS Blocks A–G/Cellular/S-GPS
Data Sheet
Description
The Avago Technologies’ ACFM-7104 is a miniature quint-
plexer that combines an extended frequency range PCS
duplexer (Blocks A-G) with a Cellular duplexer and GPS
filter. This device simplifies handset applications that
are designed for simultaneous voice service and GPS
positioning.
The ACFM-7104 features two antenna connections, one
for the duplexers and a separate antenna port for the
GPS filter. The ACFM-7104 can be used for single antenna
applications by simply connecting both antenna terminals
together with a single, external SMT component.
The ACFM-7104 is designed with Avago Technologies’
Film Bulk Acoustic Resonator (FBAR) technology. The
ACFM-7104 also utilizes Avago Technologies’ innovative
Microcap bonded-wafer, chip scale packaging tech-
nology. 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, ex-
tending battery life and talk time. The ACFM-7104 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.

Applications Information
The ACFM-7104 quintplexer has two antenna connections,
one common to the Cellular and PCS Band duplexers, and
a separate antenna for the GPS filter.
A single 5.1 nH inductor connected between Ant-1 and
Ant-2 is all that is required to match both antenna ports to
a common 50-ohm antenna.
Dual Antenna Operation
For applications in which a separate GPS antenna is
preferred, the ACFM-7104 can be connected as shown in
Figure 1.
A series-L, shunt-C network is used to match the impedance
of the Ant-1 port (duplexers) to the phone antenna. A
nominal inductance value of 5.1 nH and capacitance of
1.0 pF matches the Ant-1 port to 50 ohms.
The GPS antenna (Ant-2) is internally matched to 50 ohms
and needs no external components.
Matching Components
The L and C values shown here were selected to match
the ACFM-7104 to 50 ohms. These values should be con-
sidered to be nominal. Since every application is different,
these nominal values should be adjusted to provide the
best impedance match for the user’s particular circuit
board, performance requirements, and interface to related
components.
The L and C matching components should be located in
close proximity to the quintplexer as shown in the recom-
mended PCB layouts.
For both antenna configurations, the maximum variation
for the matching components should be ±5% for the
inductor and ±0.2 pF for the capacitor. The inductor should
be of the high Q type (e.g., Murata LQW15AN5N1D00D).
