ACFM-7107 PCS/Cellular Band Quadplexer
Data Sheet
Description
The Avago Technologies’ ACFM-7107 is a quadplexer that combines PCS and Cellular duplexers into a single, miniature package.
The ACFM-7107 features a single antenna connection, eliminating the need for antenna switching.
The ACFM-7107 is designed with Avago Technologies’ Film Bulk Acoustic Resonator (FBAR) technology. The ACFM-7107 also utilizes Avago Technologies’ innovative Microcap bonded-wafer, chip scale packaging technology. This process allows the filters to be assembled in a module with a footprint of only 4 x 7 mm with a maximum height of 1.2 mm.
Low Tx Insertion Loss of the ACFM-7107 reduces power amplifier current, extending battery life and talk time. The ACFM-7107 enhances receiver sensitivity and dynamic range with low Rx Insertion Loss and high rejection of Tx signals at the Rx ports.
The excellent power handling capability of Avago Technologies’ FBAR bulk-mode resonators supports the high Tx output power levels needed in handsets while adding virtually no distortion.
