ACMD-7617

ACMD-7617 UMTS Band 1 Duplexer Data Sheet Description The Avago ACMD-7617 is a highly miniaturized duplexer designed for use in Digital Enhanced Cordless Telecommunications (DECT) applications operating in UMTS Band 1 (1920 – 1980 MHz UL, 2110 – 2170 MHz DL). Low Insertion Loss in the Tx channel minimizes current drain from the power amplifier, while low Rx channel Insertion Loss improves receiver sensitivity. The ACMD-7617 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-7617 is designed with Avago Technologies’ innovative Film Bulk Acoustic Resonator (FBAR) technology, which makes possible ultra-small, high-Q filters 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 addi...
