Leaky-SAW IDTs formed on 36° YX-LiTaO3, and 41° and 64° YX-LiNbO3 are theoretically analyzed, providing a new equivalent circuit. Fundamental experiments show fairly good agreement between theoretical and experimental results. New high-performance SAW filters using this equivalent circuit satisfy all the specifications for cellular pocket phones, incorporating the characteristics of a SAW antenna duplexer also proposed recently
