Description
The ACMD-7701 is a miniature
duplexer designed for Korean
PCS (KPCS) handsets.
The ACMD-7701 is designed
with Agilent Technologies’ Film
Bulk Acoustic Resonator (FBAR)
technology, which makes
possible ultra-small, high-Q
filters at a fraction of their usual
size.
The ACMD-7701 also utilizes
Agilent’s innovative Microcap
bonded-wafer, chip scale
packaging technology. This
process allows the filters to be
assembled in a molded chip-onboard module that is less than
1.3 mm high with a footprint of
only 3.8 mm x 3.8 mm.
The ACMD-7701 enhances the
sensitivity and dynamic range of
KPCS receivers by providing
more than 54 dB attenuation of
the transmitted signal at the
receiver input and more than 42
dB rejection of transmitgenerated noise in the receive
band.
Maximum Insertion Loss in the
Tx channel is only 1.8 dB, which
minimizes current drain from
the power amplifier.

The excellent power handling
capability of the FBAR bulkmode resonators supports the
high output power levels needed
in KPCS handsets while adding
virtually no distortion.

Specifications are guaranteed over –30 to 85°C temperature range with the input power to the Tx port equal to or
less than +29 dBm over all Tx frequencies, unless otherwise noted.
TC is defined as case temperature, the temperature of the underside of the duplexer where it makes contact with
the circuit board.
Typical data is the average value of the parameter over the indicated frequency range. Refer to “Characterization”
section for measurement details.

Characterization
The test circuit shown in Figure
10 was used to measure typical
device performance. This
circuit is designed to interface
with coplanar Ground-SignalGround (GSG) RF probes of the
type used to test semiconductor
wafers.
The test circuit is a 7 x 7 mm
PCB with a well-grounded pad
for solder-mounting the device
under test (DUT).
Short lengths of 50-ohm
microstripline connect the DUT
to GSG probe patterns on the
board.
Phase data for s-parameters
measured with GSG probe
circuits are adjusted to place
the reference plane at the
edge of the quadplexer.
A test circuit with the DUT
mounted in place is shown in
Figure 11. S-parameters are
then measured using a network
analyzer and calibrated GSG
probe set.
