摘要： In a method for producing a multilayer ceramic substrate, a green ceramic laminate includes green conductive patterns arranged on a plurality of ceramic green sheets and portions to be formed into a plurality of multilayer ceramic substrates. Boundary-defining conductive patterns are arranged on the ceramic green sheets and along boundaries of the multilayer ceramic substrates. The boundary-defining conductive patterns have firing shrinkage characteristics that are different from those of the ceramic green sheets. During firing of the green ceramic laminate, cavities adjacent to edges of the boundary-defining conductive patterns are formed. A sintered ceramic laminate is divided at edges passing through the cavities.

摘要： A voltage controlled oscillator includes first and second variable capacitance circuits 120 and 130, and first and second capacitance switch circuits 140 and 150. A control voltage Vt is fixedly applied to the first variable capacitance circuit 120, and control signals Fsel2 and Fsel3 are fixedly applied to the first and second capacitance switch circuits 140 and 150, respectively. In a case where both of the control signals Fsel2 and Fsel3 are at a low level, the control signal Fsel1 is applied to the second variable capacitance circuit 130. In the other cases, the control voltage Vt is applied to the second variable capacitance circuit 130. As a result of this control, a high-frequency variable range is divided into two variable ranges, one based on upper frequencies and the other based on lower frequencies. This enables suppression of a frequency sensitivity without narrowing the high-frequency variable range.
