While at Murata Manufacturing, Michio Kadota conducted research and development on various Surface Acoustic Wave (SAW) devices. He achieved notable successes, including the development and mass production of TV-video IF SAW filters using ZnO film on glass, compact IF filters employing edge-reflection of Bleustein-Gulyaev-Shimizu waves, and Shear Horizontal (SH) waves using Ta interdigital tranceducer (IDT) on ST-90ºX quartz. He also pioneered the development of small SAW duplexers with low temperature coefficient of frequency (TCF) incorporating a flattened SiO2 film, high-density electrodes, and LN (LiNbO3) or LT (LiTaO3) substrates, marking the first report of TC-SAW using SiO₂. Additionally, he developed ultra-small boundary acoustic wave RF filters that eliminated the need for packaging. He further advanced the field with 4 to 6.5 GHz A1 mode Lamb wave resonators using epitaxial LN film, for which he received the IEEE Transactions on UFFC Outstanding Paper Award in 2010. After joining Tohoku university, he conducted research on ultra-wideband resonators and filters, focusing on SH₀ plate waves in LN plates, solidly mounted SH-type SAW devices, and LT thin-film on quartz hetero-acoustic layer SAW resonators. These devices offer three key advantages: high Q-factor, new zero TCF, and spurious-free operation up to 14 GHz. He has now successfully demonstrated 8 GHz harmonic SAW resonators and filters using grooved IDTs on LN, and BAW resonators operating above 9.5 GHz through innovative structural designs.
