Patent number: 6490010Abstract: Stabilized carrier recovery is achieved even at the time of a low C/N ratio by measuring the phase of a signal and controlling VCO or NCO (Numerical Controlled Oscillator) using only a period having few constellation points. At this time, false lock phenomenon is avoided as follows. That is, relatively short SYNC modulated by an already-known pattern is entered into a modulation wave, VCO or NCO oscillation frequency is swept in a wide range and sweep is stopped at a frequency in which the SYNC can be received, thereby carrying out coarse control AFC. Further, a period having long to some extent, having few constellation points is provided in the modulation wave and then, a difference between the frequency of a received modulated signal and a local oscillation signal of VCO or NCO is obtained in this period.Type: GrantFiled: May 14, 1999Date of Patent: December 3, 2002Inventors: Kazuhiko Shibuya, Junji Kumada, Yuichi Iwadate, Hiroyuki Hamazumi, Toshihiro Nomoto, Kouichi Takano, Tomohiro Saito, Shoji Tanaka, Fumiaki Minematsu, Akinori Hashimoto, Shigeyuki Itoh, Hajime Matsumura, Hisakazu Katoh, Masaru Takechi

Patent number: 6232850Abstract: A magnetostatic wave device includes a Gd3Ga5O12 substrate off-angled from a {110} plane. A magnetic thin film including a crystal of garnet is formed on the Gd3Ga5O12 substrate by liquid-phase epitaxy. A transducer operates for exciting magnetostatic wave in the magnetic thin film in response to an RF electric signal. A bias magnetic field is applied to the magnetic thin film. There is a relation as 20°≦|&thgr;1+&thgr;2|≦35°, where “&thgr;1” denotes an angle between a longitudinal direction of the transducer and a <001> orientation of the crystal in the magnetic thin film, and “&thgr;2” denotes an angle between a transverse direction of the transducer and a specified direction.Type: GrantFiled: February 24, 1999Date of Patent: May 15, 2001Assignees: Shin-Etsu Chemical Co., Ltd., Nippon Hoso KyokaiInventors: Masanori Ikari, Masayuki Tanno, Toshihiko Ryuo, Takao Kuki, Toshihiro Nomoto

Patent number: 5923228Abstract: An S/N enhancer is provided which can be formed to be small in size and in which impedance matching can easily be achieved. The S/N enhancer includes two magnetostatic wave elements. First to fourth transducers each in the shape of a single line are disposed on YIG thin films of the magnetostatic wave elements in parallel and spaced from one another. An input terminal is connected to one end of the first transducer. An attenuator is connected between the other end of the first transducer and one end of the third transducer. A 180.degree. shifter and another attenuator are connected in series between one end of the second transducer and one end of the fourth transducer. An output terminal is connected to the other end of the fourth transducer. The other ends of the second and third transducers are respectively grounded.Type: GrantFiled: March 6, 1997Date of Patent: July 13, 1999Assignee: Murata Manufacturing Co., Ltd.Inventors: Takekazu Okada, Satoru Shinmura, Fumio Kanaya, Akira Toba, Toshihiro Nomoto

Patent number: 5307516Abstract: A magnetostatic wave (MSW) signal-to-noise (S/N) enhancer includes a divider for dividing an input signal into a first and a second path signals, first and second microwave-MSW transducers for transducing the first and second path signals into the first and second path transduced signals, and a combiner for combining the first and second path transduced signals in opposite phase to each other. The first path signal contains a desired signal which is higher than a first saturation level and a noise component which is lower than the first path threshold power level. The first microwave-MSW transducer outputs the noise in linear operation and the desired signal in saturation operation. All the component signals of the second path signal including noise are lower than the second path threshold power level and are output in a linear operation by the second microwave-MSW transducer.Type: GrantFiled: September 13, 1991Date of Patent: April 26, 1994Assignee: Nippon Hoso KyokaiInventor: Toshihiro Nomoto
