ACMD-7612
Miniature UMTS Band I Duplexer
Data Sheet
Description
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 trans-
mit-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 capabil-
ity 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’ in-
novative Microcap bonded-wafer, chip scale packaging
technology. This process allows the filters to be assem-
bled 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.
