  • Microwave pulse generator
    Patent number: 6380815
    Abstract: The invention relates to a microwave pulse generator for generating microwave pulses with a pulse duration in the nanosecond range. The microwave pulse generator includes a pulse generator for generating control pulses of a constant pulse duration and a microwave oscillator generating microwave oscillations. The microwave oscillator includes a transistor amplifier, to which a frequency-determining resonant circuit and an ohmic device for reducing the resonant Q-value are connected in such a way that a control pulse of the pulse generator applied to an input terminal of the transistor amplifier causes the microwave oscillator to produce a microwave oscillation that can be tapped at an output terminal of the microwave oscillator, wherein the microwave oscillation follows at least approximately the temporal course of the control pulse.

  • Filling-level measuring device that evaluates echo signals
    Publication number: 20020020216
    Abstract: A filling-level measuring device, specifically a filling-level radar system, comprises a transmitter (1), a receiver (2) for an echo of a signal emitted by the transmitter (1), and an evaluation circuit (3) for estimating the filling level. The transmitter (1) and the receiver (2) are suitable for operation with a plurality of frequencies on the part of the emitted signal and the echo.
