Abstract
A limiter for high-frequency signals has an input, whereas the high-frequency signal is supplied to the limiter at its input. The limiter provides several limiting stages which are electrically connected to the input. Each limiting stage is a series circuit with an unbiased diode and a Zener diode which does not serve to bias the diode, so that the high-frequency signal is electrically connected to a reference ground via the one unbiased diode and the Zener diode.
Claims17
A limiter for high-frequency signals, comprising:
- an input for receiving a high-frequency signal;
- and
- at least one limiting stage which is electrically connected to the input,
- wherein the at least one limiting stage includes a series circuit with an unbiased diode and a Zener diode which does not serve to bias the diode, so that the high-frequency signal is electrically connected to a reference ground via the unbiased diode and the Zener diode.
