ACMD-7602 Datasheet | Avago Technologies

Description The Avago ACMD-7602 is a miniature duplexer designed for use in UMTS Band I handsets. Maximum Insertion Loss in the Tx channel is only 1.5 d B, which minimizes current drain from the power amplifier. Insertion Loss in the Rx channel is a maximum of 2.0 d B, improving receiver sensitivity. The ACMD-7602 enhances the sensitivity and dynamic range of WCDMA receivers by providing more than 53 d B attenuation of the transmitted signal at the receiver input and more than 43 d B rejection of transmit-generated noise in the receive band. The ACMD-7602 is designed with Avago Technologies’ 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 the FBAR bulk-mode resonators supports the high output power levels needed in handsets while adding virtually no distortion. The ACMD-7602 also utilizes Avago Technologies’ innovative Microcap bonded-wafer, chip scale packaging technology. This process allows the filters to be assembled in a molded chip-on-board module that is less than 1.2 mm high with a maximum footprint of only 2.5 mm x 3.0 mm.
