GENERAL DESCRIPTION

The MBF9042BB is the SAW antenna duplexer for the frequency range of 700 to 1000 MHz.

This SAW Duplexer integrates RF filters at Tx and Rx side, and matching circuit into PKG. This helps to save the space and weight greatly in the target application such as mobile telephone.

This SAW Duplexer has very low insertion loss by using high quality package. Due to high harmonics characteristics, total number of components at RF circuit can be minimized. Thanks to high isolation performance, high sensitivity can be expected. Low insertion loss at Tx saves the power consumption of mobile telephone which prolong the battery life.

FEATURES

• Complying Standard AMPS, IS-95, IS-136

• Thin package: less than 1.5 mm in height

• PKG I/O Impedance: 50 Ω
