摘要：
One of plurality of transmission terminals connected to a transmission filter and a receiving terminal connected to a receiving filter is a balanced type terminal, and another is an unbalanced type terminal. The transmission filter and the receiving filter includes surface acoustic wave resonators or film bulk acoustic resonators. The balanced type terminal is connected to a longitudinal mode coupled surface acoustic wave filter.
