    摘要： The invention relates to a radar sensor having a compact design, in which an emitting and receiving array (2, 3) are placed together with their feed lines (4) on the front side of an HF substrate. Active high-frequency modules (6, 7, 8, 10, 11) are placed on the rear side of the HF substrate (1). The coupling of the supply lines (4) to the high-frequency modules on the rear side is effected by high-frequency coupling devices (5).

    摘要： The invention relates to a radar transceiver comprising: at least one oscillator (110) that can be detuned using a control voltage; at least one mixer (120), and; at least one antenna (140) for transmitting and receiving extra-high frequency signals, the mixer (120) mixing the received signal with the signal of the oscillator (110) and outputting a demodulated signal. The invention is characterized in that the at least one oscillator (110), the at least one mixer (120) and the at least one antenna (140) are placed on a single chip (100) while being situated side-by-side in a plane.

    摘要： Disclosed is a device comprising a capacitor (200) having a varying capacitance t C (U) for modifying the impedance of a section of a co-planar wave guide, which can be especially used as a high-frequency microswitch. A mass line (110, 111) and a signal line (120) interrupted by an electrically conducting connecting element (121) which is at least partially unsupported are also provided. The capacitor (200) includes the electrically conducting connecting element (212) and another electrically conducting element (130) connected to the mass line (110, 111) . A structure (150) which is connected to the electrically conducting connecting element (121) is also provided. Said structure is embodied in such a way that it reduces mechanical tensions occurring in the electrically conducting connecting element (121). In another embodiment of the inventive device, the electrically conducting connecting element (121) is made of a material having a thermal coefficient of expansion which is similar to that of silicon and a modulus of elasticity which is high in comparison with metals, especially molybdenum, tantalum or tungsten. Preferably, both embodiments are combined.

    摘要： 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).

    摘要： A balanced transfer mixer, comprising a coupler element (10), which has an HF source port (12) and an antenna port (14) on one side and two diode ports (16,18) on the other side, two mixer diodes (20, 22), which are each connected between one of the diode ports (16,18), and an HF ground (24, 26), and adjustment networks (28, 30), which set the ratio between the output converted by the mixer diodes (20,22) to the output reflected and radiated via the antenna port (14) by an antenna (46) by means of controlled adjustment of the mixer diodes (20, 22). The adjustments networks (28,30) are configured to be set electronically.
