An apparatus with a rectangular waveguide to radial mode transition and method for using the same are described. In one embodiment, the apparatus comprises a radial waveguide having at least one plate; a radio-frequency (RF) launch coupled to the radial waveguide comprising a rectangular waveguide, a rectangular waveguide to coaxial transition coupled to the rectangular waveguide, and a coaxial to radial transition coupled to the rectangular waveguide to coaxial transition.

An example waveguide connector is for making a blind-mate electrical connection between a first waveguide and a second waveguide. The waveguide connector includes a male part connected to the first waveguide, where the first waveguide includes a first conductive channel, and a female part connected to the second waveguide, where the second waveguide includes a second conductive channel. The female part includes a receptacle into which the male part slides to create the blind-mate electrical connection between the first conductive channel and the second conductive channel. A self-alignment feature is on at least one of the male part or the female part. The self-alignment feature is configured to guide the male part into the receptacle while correcting for misalignment of the male part and the female part.

An assembly for a base station antenna arrangement includes: a radio having a cover with a hole and a printed circuit board (PCB) positioned below the cover, wherein the PCB has first and second contact pads; a pogo-pin connector having a spring-loaded inner contact and an outer contact that circumferentially surrounds the inner contact, wherein the inner contact extends through the hole in the cover and engages the first contact pad of the PCB; and a gasket formed of a conductive elastomer, the gasket including a lower ring and an upper ring, wherein the lower ring is positioned in the hole in the cover and engages the second contact pad of the PCB and the upper ring engages the outer contact to establish an electrical connection between the outer contact and the second contact pad, the gasket further including a skirt that extends radially outwardly from and circumferentially surrounds the upper ring, the skirt engaging the cover of the radio.

Provided are coaxial transmission line microstructures formed by a sequential build process, and methods of forming such microstructures. The microstructures include a transition structure for transitioning between the coaxial transmission line and an electrical connector. The microstructures have particular applicability to devices for transmitting electromagnetic energy and other electronic signals.

The present invention relates to a microwave signal transition component (1) having a first signal conductor side (2) and a second signal conductor side (3). The signal transition component (1) is arranged for transfer of microwave signals from the first signal conductor side (2) to the second signal conductor side (3). The transfer component (1) comprises at least one, at least partly circumferentially running, electrically conducting frame (4), a dielectric filling (5) positioned at least partly within said conducting frame (4), at least one filling aperture (6; 6a, 6b) miming through the dielectric filling, and, for each filling aperture (6; 6a, 6b), an electrically conducting connection (7; 7a, 7b) that at least partly is positioned within said filling aperture (6; 6a, 6b). The present invention also relates to a method for manufacturing a microwave signal transition component according to the above.

Structures and methods for interconnects and associated alignment and assembly mechanisms for and between chips, components, and 3D systems.

A coaxial connector mounted to a board, wherein a center conductor is provided with a contact portion in contact with the terminal of a counterpart connector. A first coupling portion couples to the contact portion and extends in the axial direction of an outer conductor. A bend portion couples to the first coupling portion and is bent in the radial direction of the outer conductor. A second coupling portion couples to the bend portion and extends in the radial direction of the outer conductor. A connecting portion couples to the second coupling portion and connects said center conductor to on-board circuitry. A first and second expanded portion produced by an expansion of a portion of the outer peripheral surface of said first and second coupling portions, is formed in the first and second coupling portions.

The present invention relates to a cavity filter and a connecting structure included therein. The cavity filter includes: an RF signal connecting portion spaced apart, by a predetermined distance, from an outer member having an electrode pad provided on a surface thereof; and a terminal portion configured to electrically connect the electrode pad of the outer member and the RF signal connecting portion so as to absorb assembly tolerance existing at the predetermined distance and to prevent disconnection of the electric flow between the electrode pad and the RF signal connecting portion, wherein the terminal portion includes: first side terminal contacted with the electrode pad; and the second side terminal connected to the RF signal connecting portion, wherein at least any one of the first side terminal and the second side terminal has a housing space in which the other side terminal is housed, and a part of the at least one side terminal is elastically deformed by an assembly force provided by an assembler, and applies lateral tension to the other side terminal while elastically supporting the other side terminal toward the electrode pad. Therefore, the cavity filter can efficiently absorb assembly tolerance which occurs through assembly design, and prevent disconnection of an electric flow, thereby preventing degradation in performance of an antenna device.
