Description

The Avago Technologies’ ACFM-7024 is a quadplexer that

combines LTE Band 2 and Band 4 duplexers into a single,

miniature package.

The ACFM-7024 features a single antenna connection, which

eliminates the need for antenna switching. All ports are

matched to 50 ohms.

The ACFM-7024 is designed with Avago Technologies’ film bulk

acoustic resonator (FBAR) technology. The ACFM-7024 also

utilizes Avago Technologies’ innovative microcap

bonded-wafer, chip scale packaging technology. This process

allows the filters to be assembled in a module with a footprint

of only 3.6 mm × 2 mm with a maximum height of 0.80 mm.

Low Tx insertion loss of the ACFM-7024 reduces power

amplifier current, which extends the battery life. The

ACFM-7024 enhances receiver sensitivity 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’ FBAR bulk-mode resonators supports the high Tx

output power levels needed mobile communications devices

while adding virtually no distortion.
