Broadcom ACMD-7612 Miniature UMTS Band I Duplexer

The Avago ACMD-7612 is a miniature duplexer designed for use in UMTS Band I handsets. Maximum Insertion Loss in the Tx channel is only 1.5 dB,
which minimizes current drain from the power amplifier. Insertion Loss in the Rx channel is a maximum of 2.0 dB, improving receiver sensitivity.
The ACMD-7612 enhances the sensitivity and dynamic range of WCDMA receivers by providing more than 53 dB attenuation of the transmitted signal at the
receiver input and more than 43 dB rejection of transmit-generated noise in the receive band.

The ACMD-7612 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-7612 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 than1.2 mm high with a maximum footprint of only 2.5 mm x 3.0 mm
