v Unbalanced-balanced conversion circuit element By www.freepatentsonline.com Published On :: Tue, 16 Jun 2015 08:00:00 EDT An unbalanced-balanced conversion circuit element includes an inductor connected in series between an unbalanced terminal and a first balanced terminal. The first balanced terminal side of the inductor is grounded via a capacitor. A capacitor is connected in series between the unbalanced terminal and a second balanced terminal. An inductor is connected between the first balanced terminal side of the inductor and the second balanced terminal side of the capacitor. In a laminate defining the unbalanced-balanced conversion circuit element, the capacitor is spaced far from a mounting surface of the laminate in comparison with other circuit elements. Full Article
v Surface acoustic wave resonator, surface acoustic wave oscillator, and electronic apparatus By www.freepatentsonline.com Published On :: Tue, 21 Jul 2015 08:00:00 EDT A surface acoustic wave (SAW) resonator and a SAW oscillator and an electronic apparatus including the resonator are to be provided. A SAW resonator includes: an IDT exciting a SAW using a quartz crystal substrate of Euler angles (−1.5°≦φ≦1.5°, 117°≦θ≦142°, 42.79°≦|ψ|≦49.57°); one pair of reflection units arranged so as allow the IDT to be disposed therebetween; and grooves acquired by depressing the quartz crystal substrate located between electrode fingers. When a wavelength of the SAW is λ, and a depth of the grooves is G, “0.01λ≦G” is satisfied. Full Article
