ACMD-7601

ACMD-7601 Miniature UMTS Band I Duplexer Data Sheet Description Features The Avago Technologies ACMD-7601 is a miniature duplexer designed for UMTS Band I handsets. The ACMD-7601 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 ACMD-7601 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 1.3 mm high with a footprint of only 3.8 mm x 3.8 mm. The ACMD-7601 enhances the sensi-tivity and dynamic range of UMTS Band I receivers by providing more than 51 dB attenuation of the transmitted signal at the receiver input and more than 45 dB rejection of transmit-generated noise in the receive band.
