I use an 7 GS/s ADC to acquire data with an frequency of 2 GHz. The input range of the device is between -0.35 and 0.35 volts. My signal is also between this range, but sometimes there is a short burst over 0.35 volts. So I have to protect the input of the ADC for signals with a higher level than 3.5 volts.
I don't think that it is a good idea to build my own small circuit with a diode protection circuit by signals with 2GHz.
How can I limit higher voltage? I tried to search for HF-Limiter, but most of the had an static attenuation.
