Abstract

The present invention relates to a component (BE) which has a first duplexer operating with acoustic waves and a second duplexer operating with acoustic waves, wherein the first and second duplexers are arranged in a single SMD housing. In addition, the invention relates to a module (MO), which interconnects such a component (BE) and at least three 90° hybrids (HYB 1 -HYB 3 ) to form an enhanced duplexer. A further aspect of the invention relates to a 2in1 hybrid, in which two 90° hybrids (HYB 3 , HYB 4 ) or one 90° hybrid (HYB 3 ) and one 180° hybrid (BAL) are arranged on a single chip.
