ACMD-7407
UMTS Band 2 Duplexer
Data Sheet
Description
The Avago ACMD-7407 is a highly miniaturized duplexer
designed for use in UMTS Band 2 (1850.48 – 1909.52 MHz
UL, 1930.48 – 1989.52 MHz DL) handsets and mobile data
terminals.
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-7407 enhances the sensi tivity 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-7407 is designed with Avago Technologies’ in-
novative 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-7407 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 size
of only 2.0 x 2.5 mm and maximum height of 0.90 mm.
The ACMD-7407 is compatible with standard 2.0 x 2.5 mm
duplexer PCB footprints.

Notes:
1. TC is the case temperature and is defined as the temperature of the underside of the Duplexer where it makes contact with the circuit board.
2. Min/Max specifications are guaranteed at the indicated temperature with the input power to the Tx port equal to or less than +29 dBm over all Tx
frequencies unless otherwise noted.
3. Typical data is the average value of the parameter over the indicated band at the specified temperature. Typical values may vary over time.
4. Integrated Insertion Loss over any 3.84 MHz channel within the band.
5. The maximum Tx Insertion Loss specification at TC = +85°C is guaranteed for input power ≤ +27 dBm. For Tx input power between +27 dBm and +29
dBm, the Tx Insertion Loss is higher by 0.2 dB. Alternatively, the Tx Insertion Loss specification is compliant to +29 dBm input power for TC ≤ 79°C.

Figure 22. Suggested PCB Layout.
A PCB layout using the principles illustrated in the figure
above is recommended to optimize performance of the
ACMD-7407.
Note: Pin 8 grounded in this example.
The transmission line dimensions shown are designed to
achieve an impedance of 50 ohms for an 80μm 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.
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-7407 mounting area
are also needed to provide adequate heat sinking for the
device.
