Overview
ACMD-7605 Miniature UMTS Band 8 Duplexer Data Sheet Description 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 sensit­ ivity 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.
