描述 Description

The Avago ACMD-7411 is a highly miniaturized duplexer designed for use in UMTS Band 2 (1850 – 1909 MHz UL, 1930 – 1989 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 to preserve CMR and simplify the interface to baseband chipsets.

The ACMD-7411 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-7411 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-7411 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 x 2.0 mm and height of 0.9 mm. The ACMD-7411 is compatible with standard 1.6 x 2.0 mm duplexer PCB footprints.
