Abstract:
Electronic arrangement (100) comprising a component carrier (110) with a first (111) and a second (112) main surface, in which component carrier a first aperture (120, 130) is arranged, the main direction of which extends from the first main surface towards the second main surface, and an electronic component (150, 160) which is arranged and retained in the aperture. The material of the component carrier (110) has essentially at least the same thermal expansion coefficient as the electronic component (150, 160), and the component carrier (110) can be used to retain the component in the aperture (120, 130). The extent of the aperture (120, 130) is the same as the extent of the component (150, 160) in a direction running between the main surfaces (111, 112) of the component carrier at right angles to the main surfaces. The component is positioned in the carrier (110) in such a manner that the extents of the component and the aperture in said direction coincide. The invention also relates to the component carrier and a method of producing the arrangement.
Abstract:
The present invention relates to a carrier (10) intended for one or several electronic components (14, 15) and comprising spaces (13) provided for said components on at least one surface (11). The carrier (10) comprises at least partly conductive LTCC (Low Temperature Cofire Ceramic) material with good thermal conduction capacity, so that the carrier besides providing mechanical support for the components also conducts heat generated by the components.
Abstract:
A method for arranging one or more electronic components (100) on a carrier (200). The electronic components have a number of contact points (110) arranged on a first surface (120). The carrier has a second main surface (210) and a third main surface (220). In the carrier there are also arranged one or more first apertures (230) with a depth extending from the second main surface towards the third main surface. The method comprises the stages: arranging of connecting means (130) on the contact points, where the connecting means have a first end (140) connected to one of the contact points and a second end (150) at a distance from the contact point, arranging of the electronic components in the apertures in the carrier so that the connecting means are pointed away from the third main surface of the carrier, application of a dielectric layer (300) on the second main surface of the carrier, where the dielectric layer also covers the electronic component, exposure of the second end of the connecting means in the dielectric layer, and connection of the second end of the connecting means to circuit paths (310) arranged on the free surface of the dielectric layer.
Abstract:
It is provided a waveguide E-plane band-pass filter comprising a tubular, electrically conductive waveguide body. An electrically conductive foil is arranged in the waveguide body and extending along a longitudinal direction of the waveguide body, the foil comprising a plurality of resonator openings. Furthermore, the waveguide body comprises at least one ridge protruding from an inner wall of the waveguide body and extending longitudinally along the longitudinal direction of the waveguide body. The foil is in mechanical contact with said at least one ridge and arranged to divide an inner volume of the waveguide body into two portions. It is also provided a diplexer, a radio transceiver, and a method for filtering a signal using such a filter.
