Publication number: 20090042522Abstract: A transmitter includes a board, an electronic circuit provided on the board for outputting a transmission signal, an amplifier provided on the board for amplifying the transmission signal, an antenna terminal provided on the board and arranged to be connected to an antenna, and a transmission path arranged along a border of the board. The transmission path is connected to an output port of the amplifier and the antenna terminal. The transmission path supplies the amplified transmission signal to the antenna terminal. This transmitter prevents the transmitting signal from entering into other circuits, and thus, has preferable transmission characteristics.Type: ApplicationFiled: December 21, 2006Publication date: February 12, 2009Applicant: Matsushita Electric Industrial Co., Ltd.Inventors: Yukio Sakai, Hiroki Iwamiya, Yuji Osumi

Patent number: 7299015Abstract: According to a transmitting output control circuit, one end of a coupling capacitor and one end of main line of a directional coupler are coupled with an output terminal of a power amplifier. A switch for coupling the other end of the coupling capacitor and one end of a sub line of the directional coupler with an anode of a first diode or a second terminating resistor is formed in a power amplifying apparatus. Any one of the coupling capacitor and the directional coupler is coupled by switching the switch. By using this structure, the stable transmitting power control circuit, which can be used in a wide dynamic range necessary for detecting a transmitting output signal level, can be provided.Type: GrantFiled: May 18, 2005Date of Patent: November 20, 2007Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Hiroki Iwamiya, Yuji Osumi

Patent number: 7120409Abstract: The high-frequency module of the present invention is formed of two sections: first high-frequency circuit 5 having a first filter circuit; and second high-frequency circuit 6 having a second filter circuit. At least any one of the two high-frequency circuits has a conductive case. The structure is highly effective in attenuating a spurious signal, thereby solving the problem that the output level of the spurious signal fed from the high-frequency module is undesirably increased.Type: GrantFiled: July 23, 2003Date of Patent: October 10, 2006Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Yoshikuni Fujihashi, Hiroki Iwamiya, Yuji Osumi

Patent number: 7019709Abstract: An antenna device has a first radiation plate and a second radiation plate of which a diameter or one side is about ½ wavelength in electrical length disposed on a ground plate at an arbitrary interval. A first power feed port and a second power feed port are provided on the first radiation plate and are disposed so that straight lines linking each power feed port position and a middle point of the first radiation plate may be orthogonal to each other. A third power feed port and a fourth power feed port are provided on the second radiation plate and are disposed so that straight lines linking each power feed port position and a middle point of the second radiation plate may be orthogonal to each other. The straight lines are disposed to have an angle of 45 degrees to a straight line linking the first power feed port position and the middle point of the first radiation plate and to a straight line linking the second power feed port position and the middle point of the first radiation plate.Type: GrantFiled: August 21, 2003Date of Patent: March 28, 2006Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Susumu Fukushima, Yuji Osumi
