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.
