The Avago ACFM-7024 is a highly integrated quadplexer device that combines LTE Band 2 and Band 4 duplexers in a single miniature package. The device features a single antenna connection, eliminating the need for antenna switching. High isolation between bands enables the use of carrier aggregation. All ports are matched to 50 ohms.
Low Tx insertion loss of the ACFM-7024 reduces power amplifier current drive, thereby extending battery life. The device 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's FBAR bulk-mode resonators supports the high Tx output power levels needed for modern mobile devices while adding minimal distortion.
