The Avago Technologies’ ACMD-7605 is a miniature duplexer designed for use in UMTS Band 8 (880 – 915 MHz UL, 925 – 960 MHz DL) handsets and mobile data terminals.

The ACMD-7605 enhances the sensitivity and dynamic range of handset receivers by providing more than 51 dB attenuation of the transmitted signal at the receiver input and more than 48 dB rejection of transmit-generated noise in the receive band.

Maximum Insertion Loss in the Tx channel is only 3.5 dB, which minimizes current drain from the power amplifier. Insertion Loss in the Rx channel is a maximum of 4.0 dB, thus improving receiver sensitivity.

The ACMD-7605 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-7605 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 3.0 mm x 3.0 mm.
