FBAR Duplexer for US PCS Band
Data Sheet
General Description
The HPMD-7905 is a miniaturized duplexer designed
for US PCS handset, designed using Avago Technolo-
gies’ Film Bulk Acoustic Resonator (FBAR) Technol-
ogy. 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 mm
The HPMD-7905 enhances the sensitivity and dy-
namic range of CDMA receivers, providing more than
49 dB attenuation of transmitted signal at the receiver
input, and more than 37 dB rejection of the transmit-
generated noise in the receive band. Typical inser-
tion loss in the Tx channel is only 2.5 dB, minimizing
current drain from the power amplifier. Typical in-
sertion loss in the Rx channel is 3.0 dB, improving
receiver sensitivity.
Avago’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 pow-
ers needed in PCS handsets, with virtually no added
distortion.
