A first high-frequency line (3a, 3b) coupled or to be coupled with the high-frequency antenna is arranged in a first conductor plane, while a second high-frequency line (4a, 4b) coupled or to be coupled on the device side is arranged in a second conductor plane of the multi-layer circuit board (2). The multi-layer circuit board (2) has an electrically insulating circuit board core layer (6), wherein the first and second conductor planes extend on the same of the two faces of the circuit board core layer (6), and wherein the second high-frequency line (4a, 4b) coupled or to be coupled on the device side is arranged at a larger distance from the circuit board core layer (6) than the first high-frequency line (3a, 3b), and furthermore the second high-frequency line (4a, 4b) is arranged on an outer surface of the multi-layer circuit board (2). The antenna coupler (1) comprises an electrically conductive shielding structure (5), which extends partially on the opposite other of the two faces of the circuit board core layer (6) and is designed to shield the first high-frequency line (3a, 3b) and metal parts on the device side that are not part of the antenna coupler (1) from an interaction while high-frequency signals are conducted.

Abstract: The invention relates to a device comprising a capacitor (200) for altering the impedance of a section of a coplanar waveguide, whereby the capacitance of the capacitor (200) can be altered. The capacitor (200) comprises, at least in part, a first electrically conductive connection (130), a second electrically conductive connection (131), and a third electrically conductive connection (121). The signal line (120) of the section of the waveguide is interrupted along a predetermined length (122). The first connection (130) connects the grounding lines (110, 111) of the waveguide, the second connection (131) also connects the grounding lines (110, 111) of the waveguide, and the third connection (121) connects both portions of the interrupted signal line (120).

Abstract: The present invention relates to an arrangement (1) and a method in a receiver in a multi-mode mobile ratio (m), wherein the intention is to design the receiver so that it uses the same hardware to process several different channel bandwidths corresponding to the different networks used by the radio (m). This is done by changing a sampling frequency (fs) which controls a digital filter unit (25) situated in the digital part of the receiver. The changing of the sampling frequency (fs) results in that the bandwidth of the digital filter unit (25) is scaled accordingly, wherein the desired channel bandwidth at baseband of the radio network (GSM1900, AMPS) to be used by the radio (m) is selected in the digital filter unit (25). As a complement, the digital filter unit (25) can be implemented with a programmable function, where a change of parameters and/or filter structure inside the digital filter unit (25) can be used to adjust the filter bandwidth.

Abstract: A plurality of one-quarter wavelength coplanar resonators (5a) to (5d) are formed in series on a dielectric substrate (1), and coplanar input/output terminal sections (4a) and (4b) are formed on the dielectric substrate at opposite ends of the series connection for coupling with resonators (5a) and (5d), respectively. A center conductor line width w 1 and the ground conductor spacing d 1 of each of the resonators (5a) to (5d) are set based on the maximum current density previously determined on the basis of a relationship between a maximum current density which is set for materials of the dielectric substrate and the ground conductors and the ratio of the center conductor line width with respect to the ground conductor spacing. Maintaining the accuracy of design is facilitated and a reduction in the maximum current density in the resonator is enabled.
