Patent number: 6559729Abstract: A miniaturized oscillator that is manufactured with greatly reduced production time and cost includes transmission lines defining resonance circuits provided on a circuit assembly board. In this state, the impedance of each transmission line is measured. Then, according to the transmission line impedance, chip components having impedances necessary to obtain a predetermined frequency are selected and mounted on the circuit substrate. With this arrangement and method of formation, the resulting oscillator oscillates at the desired oscillation frequency and it is not necessary to trim the transmission lines in order to achieve this result. Since the oscillator does not require time to make frequency adjustments and does require use of a trimming apparatus, no deterioration in the electric characteristics due to laser trimming occurs. In addition, it is unnecessary to provide an electrode land for making frequency adjustments. As a result, the entire oscillator is miniaturized.Type: GrantFiled: March 26, 2001Date of Patent: May 6, 2003Assignee: Murata Manufacturing Co., Ltd.Inventors: Shinji Goma, Masao Uno

Patent number: 6456169Abstract: A voltage-controlled oscillator has a frequency of oscillation that is varied using a substrate on which the same circuit pattern as that of the voltage-controlled oscillator is printed. In a resonant circuit included in the voltage-controlled oscillator, a first land is arranged substantially parallel to an inductor. A second land is arranged substantially parallel to the inductor and to a variable-capacitance diode. The capacitances of capacitors attached to the first land and second land are changed in order to vary the frequency of oscillation of the voltage-controlled oscillator. The frequency of oscillation can be varied without the necessity of scraping the inductor through which a major signal passes. Therefore, electrical characteristics of the voltage-controlled oscillator are not degraded and the frequency of oscillation is very steady. The frequency of oscillation can be varied merely by changing the capacitances of the capacitors attached to the first and second lands.Type: GrantFiled: December 22, 2000Date of Patent: September 24, 2002Assignee: Murata Manufacturing Co., Ltd.Inventors: Teruaki Oshita, Shinji Goma

Patent number: 6388517Abstract: An input change-over amplifier is capable of effecting a change-over in outputting two signals having different frequencies, without lowering the signal levels thereof. Two signals having different frequencies are fed into two input terminals of an amplifying element. When a signal is input through one input terminal, the other input terminal is grounded. When a signal is input through the other input terminal, the above one input terminal is grounded. In this way, it is possible to effect a change-over in outputting two signals having different frequencies, without lowering the signal levels thereof. Further, since two signals can be fed into an amplifying element through different paths, it is not necessary to provide a matching circuit at a connection point of signal paths. Therefore, the number of required electronic parts can be reduced, an oscillator which is compact in size can be manufactured, and a necessary circuit can be designed within only a short time.Type: GrantFiled: June 21, 2000Date of Patent: May 14, 2002Assignee: Murata Manufacturing Co., Ltd.Inventors: Shinji Goma, Yoshiyuki Mashimo
