ACMD-4104 umts band 4 duplexer with balanced rx port product brief description the avago ACMD-4104 is a highly miniaturized duplexer designed for use in umts band 4 (1710 C 1755 mhz ul, 2110 C 2155 mhz dl) handsets and mobile data terminals. low insertion loss in the tx channel minimizes current drain from the power amplifer, while low rx channel insertion loss improves receiver sensitivity. the rx port is balanced (100 ohms) to preserve common-mode rejection ratio (cmrr) and simplify the interface to baseband chipsets. the ACMD-4104 enhances the sensitivity and dynamic range of handset receivers by providing high isolation of the transmitted signal from the receiver input and high rejection of transmit-generated noise in the receive band. the ACMD-4104 is designed with avago technologies innovative 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 fbar bulk-mode resonators supports the high output power levels used in mobile communications applications, while adding virtually no distortion. the ACMD-4104 also utilizes avago technologies advanced microcap bonded-wafer, chip scale packaging technology. this process allows the flters to be assembled into a molded chip-on-board module with an overall size of only 1.6 2.0 mm and height of 0.9 mm. the acmd- 4104 is compatible with standard 1.6 2.0 mm duplexer pcb footprints. functional block diagram features ? miniature size C 1.6 2.0 mm size C 0.9 mm height C standard 1.6 x 2.0 pcb footprint ? balanced rx port, 100 ? ? high isolation ? high power rating C 33 dbm abs. max. tx power ? environmental C rohs 6 compliant C halogen-free C tbbpa-free specifcations ? rx band performance, C20 to +85 c C insertion loss: 1.9 db max.
