ACMD-7605 miniature umts band 8 duplexer data sheet description the avago technologies ACMD-7605 is a miniature duplexer designed for use in umts band 8 (880 C 915 mhz ul, 925 C 960 mhz dl) handsets and mobile data terminals. the ACMD-7605 enhances the sensi tivity and dynamic range of handset receivers by providing more than 51 db attenuation of the transmitted signal at the receiver input and more than 48 db rejection of transmit-generated noise in the receive band. maximum insertion loss in the tx channel is only 3.5 db, which minimizes current drain from the power amplifer. insertion loss in the rx channel is a maximum of 4.0 db, thus improving receiver sensitivity. the ACMD-7605 is designed with avago technologies film bulk acoustic resonator (fbar) technology, which makes possible ultra-small, high-q flters at a fraction of their usual size. the excellent power handling capability of the fbar bulk-mode resonators supports the high output power levels needed in handsets while adding virtually no distortion. the ACMD-7605 also utilizes avago technologies innova - tive microcap bonded-wafer, chip scale packaging tech - nology. this process allows the flters to be assembled in a molded chip-on-board module that is less than 1.2 mm high with a maximum footprint of only 3.0 mm x 3.0 mm. functional block diagram ant port 3 tx rx port 1 port 2 features ? miniature size C 3.0 x 3.0 mm max footprint C 1.2 mm max height ? high power rating C 33 dbm abs max tx power ? rohs compliant specifcations ? rx band performance, 925-960 mhz, C 30 to +85c C insertion loss: 4.0 db max C rx noise blocking: 48 db min ? tx band performance, 880-915 mhz, C 30 to +85c C insertion loss: 3.5 db max C tx interferer blocking: 51 db min applications handsets or data terminals oper ating in umts band 8 frequency range.
