avago technologies - 1 - description the avago ACFM-2021 is a highly miniaturized diplexer designed to allow a common antenna to be used for simultaneous reception in band 4 (2110 mhz to 2170 mhz) and band 25 (1930 mhz to 1995 mhz). this diplexer also enables co-banding between umts bands 1 and 4. in addition to maintaining hi gh isolation between band 1/4 and band 25 rx signals, the ACFM-2021 also provides high rejection of nearby interferers to minimize the opportunity for intermodulation products. low insertion loss in the rx pass bands maximizes receiver sensitivity. the ACFM-2021 is designed with avago technologies' innovative film bulk acoustic resonator (fbar) technology, which makes possible ultra-small, hi gh-q filters at a fraction of their usual size. the excellent power handling capability of fbar bulk-mode resonators suppor ts the high linearity needed in mobile communications applications. the ACFM-2021 also uses avago technologies' advanced microcap bonded-wafer, chip scale packaging technology. this process allows the filters to be assembled into a molded chip-on-board module with an overall size that is compatible with standard 1.4 mm 1.8 mm duplexer/diplexer pcb footprints. features ? miniature size 1.4 mm 1.8 mm size 0.80 mm maximum height standard 1.4 mm 1.8 mm pcb footprint ? all ports 50 , no external matching needed ? allows co-banding between umts bands 1 and 4 ? environmental rohs compliant halogen free tbbpa free applications smartphones, tablets, and mo bile/portable communications devices simultaneously receiving umts bands 1/4 and band 25. functional block diagram ordering information part number number of devices container ACFM-2021-blk 100 tape strip or anti-static bag ACFM-2021-tr1 3000 178 mm (7-inch) reel # b o e 3 y 1 p s u 1 j o
