ACFM-7104

ACFM-7104 Quintplexer for PCS Blocks A–G/Cellular/S-GPS Data Sheet Description The Avago Technologies’ ACFM-7104 is a miniature quintplexer that combines an extended frequency range PCS duplexer (Blocks A-G) with a Cellular duplexer and GPS filter. This device simplifies handset applications that are designed for simultaneous voice service and GPS positioning. The ACFM-7104 features two antenna connections, one for the duplexers and a separate antenna port for the GPS filter. The ACFM-7104 can be used for single antenna applications by simply connecting both antenna terminals together with a single, external SMT component. The ACFM-7104 is designed with Avago Technologies’ Film Bulk Acoustic Resonator (FBAR) technology. The ACFM-7104 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 and maximum height of 1.2 mm. Low Tx Insertion Loss reduces power amplifier current, extending battery life and talk time.The ACFM-7104 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.
