General Description
The HPMD-7903 is a miniaturized
duplexer designed for US PCS handset,
designed using Agilent Technologies’
Film Bulk Acoustic Resonator (FBAR)
Technology. The HPMD-7903 features
a very small size: it is less than 2 mm
thick and has a footprint of only 5.6 x
11.9 mm
2.
The HPMD-7903 enhances the sensi-
tivity and dynamic range of CDMA
receivers, providing more than 50 dB
attenuation of transmitted 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.
