a GPS filter. This device simplifies handset applications
positioning.
The ACFM-7102 is designed with Avago Technologies鈥?/div>
Film Bulk Acoustic Resonator (FBAR) technology. The
ACFM-7102 also utilizes Avago Technologies鈥?innovative
Microcap bonded-wafer, chip scale packaging technology.
This process allows the filters to be assembled in a
module that is less than 1.2 mm high with a footprint of
only 5 mm x 8 mm.
Low Tx Insertion Loss reduces power amplifier current,
extending battery life and talk time. The ACFM-7102
enhances receiver sensi-tivity and dynamic range with
low Rx Insertion Loss and high rejection of Tx signals at
the Rx ports.
The excellent power handling capability of Avago
Technologies鈥?FBAR bulk-mode resonators supports the
high Tx output power levels needed in handsets while
adding virtually no distortion.
