High Rejection Tx Filter for US PCS Band
Data Sheet
Description
This product is a high rejection full band transmit
filter designed for US PCS handsets. Its performance
rivals splitband surface acoustic wave (SAW) trans-
mit filters. Since the rejection is provided by a single
filter, no switches are required, saving board space
and external components, eliminating switch loss,
and reducing programming complexity.
In typical cellular phone architectures, the transmit
filter fits between the driver amplifier and the
power amplifier. This filter reduces the noise in the
Rx band being amplified by the transmit chain,
enhancing receiver sensitivity. High rejection keeps
unwanted signals out of the receive path.
Avago’s thin-Film Bulk Acoustic Resonator (FBAR)
technology makes possible high-Q filters at a
fraction of their usual size.
