摘要:
A radar transceiver, including at least one oscillator tunable using a control voltage, at least one mixer, and at least one antenna for transmitting and receiving ultra-high-frequency signals, the mixer mixing the receive signal with the signal of the oscillator and outputting a demodulated signal, and in which the at least one oscillator, the at least one mixer, and the at least one antenna are situated on a single chip located next to one another in one plane.
摘要:
In a microwave antenna a dielectric carrier having a strip line is provided. A funnel-shaped or horn shaped waveguide radiator is integrated into a metallic cover, and it is situated above the strip line. A transformation element is provided for the transition from the strip line to the aperture of the waveguide radiator.
摘要:
A short-range radar system includes short-range radar sensor means and means (41) for HF-impulse generator for the sensor means. The means for HF-impulse generation are embodied for emitting impulses with adjustable pulse duration (51, 53).

摘要:
A coupling element for an HF strip line structure on an HF substrate, implemented in thin-layer technology as a finger coupler structure on a silicon support is described. The bonding to the strip line tracks of the HF strip line structure is effected via metallizations, in particular in the form of spacers.
