Agilent ACPF-7001 High Rejection Tx Filter for US PCS Band
Data Sheet
Features • High rejection from a single filter with no switches required
www.DataSheet4U.com
Description This product is a high rejection full band transmit filter designed for US PCS handsets. Its performance rivals splitband surface acoustic wave (SAW) transmit 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.
