ACMD-7606
UMTS Band 8 Duplexer
Data Sheet
Description
Features
The Avago ACMD-7606 is a highly miniaturized duplexer
designed for use in UMTS Band 8 (880 – 915 MHz UL, 925 –
960 MHz DL) handsets and mobile data terminals.
x Miniature Size
– 2.0 x 2.5 mm Max size
– 0.95 mm Max Height
– Standard 2 x 2.5 mm PCB footprint
Low Insertion Loss in the Tx channel minimizes current
drain from the power amplifier, while low Rx channel
Insertion Loss improves receiver sensitivity.
The ACMD-7606 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-7606 is designed with Avago Technologies’
innovative Film Bulk Acoustic Resonator (FBAR) technology, which makes possible ultra-small, high-Q filters at
a fraction of their usual size. The excellent power handling
capability of FBAR bulk-mode resonators supports the
high output power levels used in mobile communications
applications, while adding virtually no distortion.
The ACMD-7606 also utilizes Avago Technologies’
advanced Microcap bonded-wafer, chip scale packaging
technology. This process allows the filters to be assembled
into a molded chip-on-board module with an overall
maximum size of 2.0 x 2.5 mm and maximum height of
0.95 mm. The ACMD-7606 is compatible with standard 2.0
x 2.5 mm duplexer PCB footprints.

Figure 24. Suggested PCB Layout
A PCB layout using the principles illustrated in the figure
above is recommended to optimize performance of the
ACMD-7606.
The transmission line dimensions shown are designed to
achieve an impedance of 50 ohms for an 80Pm thick PCB
layer with a dielectric constant of 3.4. If other PCB materials
or thicknesses are used, the 0.25 mm gap spacing may
need to be adjusted to retain a Zo of 50 ohms.
It is important to maximize isolation between the Tx and
Rx ports.
9
High isolation is achieved by: (1) maintaining a continuous
ground plane around the I/O connections and duplexer
mounting area, and (2) surrounding the I/O ports with
sufficient ground vias to enclose the connections in a
“Faraday cage.”
The ground vias under the ACMD-7606 mounting area
are also needed to provide adequate heat sinking for the
device.
