New miniature high performance duplexers by Avago
Avago Technologies today announced three new miniature high performance duplexers for use in UMTS Bands 2, 4, and 8 handsets and data terminals. Avago's ACMD-7410/7609/7606 duplexers are low insertion loss, high isolation and high rejection duplexers that are achieved using Avago's proprietary Film Bulk Acoustic Resonator (FBAR) technology. Avago's innovative Microcap bonded wafer technology allows these duplexers to be assembled in a molded chip-on-board module that is less than 0.95 mm high with a footprint of 2.0 by 2.5 mm.
These latest additions to Avago's family of miniature UMTS duplexers have been designed to enhance the sensitivity and dynamic range of handset receivers by providing high isolation of transmitted signals from the receiver input, and high rejection of transmit-generated noise in the receive band. Moreover, the superior power handling capability of the FBAR bulk-mode resonators designed into these duplexers support the high output power levels used in mobile communications applications while adding virtually no distortion.
Avago's ACMD-7410 is a multi-mode duplexer designed for use in UMTS Band 2 and CDMA PCS applications with the receive channel capable of being used for GSM1900 Rx co-banding. The ACMD-7609 is a multi-mode duplexer for use in UMTS Band 4 duplexer and CDMA AWS-1 applications. Completing the trio of new duplexers from Avago is the ACMD-7606, which is designed for use in UMTS Band 8 handsets and mobile data terminals.
