  • Publication number: 20240038754
    Abstract: To reduce the chip size of a chip-type electronic component including a capacitor and an inductor. A chip-type electronic component includes a capacitor constituted by a lower electrode pattern, an upper electrode pattern, and an insulating layer, an insulating layer covering the capacitor, and an inductor pattern disposed on the insulating layer. The inductor pattern has a section overlapping the capacitor, whereby an auxiliary capacitor is added. The inductor pattern is thus made to partly overlap the capacitor, so that a larger inductance can be obtained with a small chip size. In addition, characteristics can also be improved by auxiliary capacitance.

  • Publication number: 20160248141
    Abstract: A directional coupler including a main line having an input terminal and an output terminal, and a sub-line having a coupling terminal and an isolation terminal, the main line, the sub-line, the input terminal, the output terminal, the coupling terminal and the isolation terminal being disposed within a laminate, wherein the main line and the sub-line extend in a loop shape in parallel with and spaced apart from each other by a gap such that electromagnetic coupling is generated therebetween and such that the main line is positioned outside the sub-line on a coupling layer, the input terminal, the output terminal, the coupling terminal and the isolation terminal are disposed outside the main line, and the main line is interposed between the output terminal and the sub-line.

  • Publication number: 20150263406
    Abstract: A directional coupler includes a main line and a subline. The main line connects an input port and an output port. The subline connects a coupling port and a terminal port. The subline includes a first coupling line section connected to the terminal port, a second coupling line section connected to the coupling port, and a low-pass filter. The low-pass filter includes an inductor provided between the first and second coupling line sections, a first capacitor having an end connected to the connection point between the inductor and the second coupling line section, a resistor connecting the other end of the first capacitor to the ground, and a second capacitor connecting the connection point between the inductor and the first coupling line section to the ground.
