Abstract
We propose new structures of one-chip type SAW duplexers where Tx and Rx SAW ladder filters as well as isolation networks are fabricated together on a single 36° LiTaO3 piezoelectric substrate. The new SAW duplexer can overcome the difficulty in fabrication of conventional SAW duplexers while providing the performance matching that of conventional duplexers. Validity of the structure is verified through numerical simulation and experiments.
