Description

The Avago Technologies' ACFM-7210 is a quadplexer that

combines Band Class 1 and Band Class 0 duplexers into a

single, miniature package.

The ACFM-7210 features a single antenna connection, which

eliminates the need for antenna switching. All ports are

matched to 50 ohms.

The ACFM-7210 is designed with Avago Technologies' film bulk

acoustic resonator (FBAR) technology. The ACFM-7210 also

uses 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 mm ×

3 mm with a maximum height of 1.05 mm.

Low Tx insertion loss of the ACFM-7210 reduces power

amplifier current, which extends battery life. The ACFM-7210

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 for mobile communications

devices while adding virtually no distortion.
