• Tx Band: 1850-1910 MHz
Typical performance:
The HPMD-7905 is a miniaturized
duplexer designed for US PCS
handset, designed using Agilent
Technologies’ Film Bulk Acoustic
Resonator (FBAR) Technology.
The HPMD-7905 features a very
small size: it is less than 2 mm
thick and has a footprint of only
5.6 x 11.9 mm2.
Tx interferer blocking: 54dB
Insertion Loss: 2.5 dB
• 30 dBm Tx power handling

transmitted signal at the receiver
input, and more than 37 dB
rejection of the transmit-
port numbers are circled
generated noise in the receive
band. Typical insertion loss in
the Tx channel is only 2.5 dB,
minimizing current drain from
the power amplifier. Typical
insertion loss in the Rx channel
is 3.0 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.
