Latest Patents

Kazuo Ono holds a patent for a high frequency narrow-band multi-mode filter. This invention involves a high frequency narrow-band pass multi-mode filter constructed in such a manner that surface acoustic wave (SAW) resonators of single sideband wave (SSBW) are closely disposed to each other on a single piezo-electric substrate. This design generates different vibration modes of varying resonance frequencies. The conditions under which the resonators are acoustically coupled to each other have been experimentally determined, ensuring the effectiveness of the filter. To minimize the ohmic loss of a very narrow common bus bar, the number of strip pairs of electrodes in both interdigital transducers (IDTs) is minimized. Reflectors are provided on both sides of the IDTs to compensate for the reduction of the Q value. Additionally, a part of the bus bar for the IDT electrodes is formed integral with some or all of the gratings of the reflectors, allowing for high flexibility in the positioning of the grating electrodes with respect to lead terminals.
