Description
The ACMD-7401 is a miniaturized
duplexer designed using Agilent's
Film Bulk Acoustic Resonator
(FBAR) technology. The ACMD-
7401 is the first duplexer built
with Agilent's innovative
Microcap bonded-wafer chip
scale packaging technology. This
process allows the ultra small
filters to be assembled in a
molded chip-on-board (MCOB)
module that is less than 1.4 mm
high with a 5 x 5 mm footprint.
The ACMD-7401 enhances the
sensitivity and dynamic range of
CDMA receivers, providing more
than 50 dB attenuation of transmit-
ted signal at the receiver input, and
more than 40 dB rejection of the
transmit-generated noise in the
receive band. Typical insertion loss
in the Tx channel is only 1.8 dB,
minimizing current drain from the
power amplifier. Typical insertion
loss in the Rx channel is 2.2 dB,
improving receiver sensitivity.
Agilent’s thin-film Bulk Acoustic
Resonator (FBAR) technology
makes possible high-Q filters at a
fraction their usual size. The
excellent power handling of the
bulk-mode resonators supports
the high output powers needed in
PCS handsets, with virtually no
added distortion.
