Abstract:
A high-frequency module comprising:an insulating substrate comprising a plurality of ceramic thin plates stacked in layers; and an insulating layer disposed on a top surface of the insulating substrate; wherein a thin-film circuit is disposed on a top surface of the insulating layer, the thin-film circuit comprising a wiring pattern and an electrical part comprising one of a resistor and a capacitor, the wiring pattern being formed of a thin film, the electrical part being connected to the wiring pattern and being formed of a thin film; wherein the insulating substrate has at least one conductive member disposed between the layers forming the insulating substrate, a first connection conductor and a second connection conductor disposed in a thickness direction, and an electrode disposed on a side surface of the insulating substrate with the electrode being connected to the conductive member; wherein a top end of the first connection conductor has a first protrusion, a top end of the second connection conductor has a second protrusion, the first and second protrusions protrude from the top surface of the insulating substrate, each of the first and second protrusions is flush with or protrudes from the top surface of the insulating layer, and a top end of each of the first and second protrusions does not have the insulating layer formed thereon, wherein the first and second protrusions are connected to the wiring pattern; and wherein the second connection conductor is connected to an integrated circuit chip accommodated inside the insulating substrate.
