Abstract:
A signal line includes, in order from a coaxial line side, a first section, a second section, and a third section. A width of a signal conductor in the second section is constant, is less than or equal to a width of the signal conductor in the first section, and is greater than a width of the signal conductor in a center portion of the third section. A distance between the signal conductor and each first ground conductor is constant in the second section, is less than the distance in the first section, and is greater than the distance in the center portion of the third section. The second section has a length of from 1/3 times to 3/2 times a distance H between the signal conductor and a second ground conductor on a side opposite to the coaxial line from a position at which a distal end portion of a pin terminal is present as viewed in a direction perpendicular to a first surface.
Abstract:
An electronic component mounting package includes a dielectric substrate between first portions of a pair of signal terminals that protrude from one side in a thickness direction from a first face of a base body. This dielectric substrate has a height lower than a height of the first portions. When an electronic component is mounted, a bonding wire is connected to a tip of each of the first portions to electrically connect the first portion to the electronic component.

A high frequency wiring board (4) includes a dielectric substrate (4a), a line conductor (4b) for high frequency signal transmission formed on a first surface of the dielectric substrate (4a) from a connection end (4bc) to an end (4ba), a ground conductor (4c) which is disposed aligned with one side (4bb) of the line conductor (4b) with a distance therebetween, and is disposed so as to cross over a hypothetical extension line extending from the end (4ba) in parallel with a line direction of the line conductor (4b), and a terminating resistor (4d) configured to electrically connect an end portion of the line conductor (4b) and the ground conductor (4c).
Abstract:
A coaxial line includes a central conductor long in one direction, an outer peripheral conductor, and a dielectric located therebetween and having a first end face facing a transmission line. A wall body includes an opening leading to the first end face and including an annular space contacting the first end face. An outer diameter of the annular space is larger than that of a space opposite the first end face in the opening. The central conductor includes a first section having a first thickness and at least partially projecting from the first end face and a second section having a second thickness smaller than the first thickness and located within the dielectric; an end of the first section on an anti-projection side is located between the first end face and a specific position within the dielectric in a longitudinal direction of the central conductor. The specific position is a position separated from the first end face toward the inside of the dielectric by 1/8 of an effective wavelength of a transmission signal.
Abstract:
A high-frequency module has a wiring board including a dielectric substrate, a line conductor that is formed on a first surface of the dielectric substrate, and a first grounding conductor layer that is formed on a second surface opposed to the first surface of the dielectric substrate, and that has a first opening and a second opening disposed around the first opening; and a waveguide that is connected to the second surface, has an opening opposed to the first opening, and is electromagnetically coupled to the line conductor. The wiring board has a vertical choke portion that at least partially extends from the second opening in a direction perpendicular to the second surface. Furhermore, a horizontal choke portion is formed between the wiring board and the waveguide, along the second surface between the opening of the waveguide and the second opening.

Abstract:
A semiconductor device mounting board includes a first substrate, a second substrate, a single line, a groove, a feedthrough conductor, and a side conductor. The first substrate includes a mount area and a peripheral area. The second substrate is located in the peripheral area to align with an outer edge of the first substrate and surrounds the mount area. The signal line extends on an upper surface of the second substrate from an inner edge to an outer edge of the second substrate. The groove extends on a side surface of the first substrate from a lower surface to an upper surface of the first substrate. The feedthrough conductor is inside the second substrate and connected to the signal line. The side conductor is on an inner surface of the groove and electrically connected to the feedthrough conductor. The groove is inward from the outer edge of the second substrate.
