[SOLVED] Zener Diodes (clipping schematic) on a 50 ohm matched RF circuit

[LandLack]

Hi, I need to use two zener diodes on this configuration (https://en.wikipedia.org/wiki/Clipper_(electronics)) on the output of a 50 ohm matched RF circuit (1.4 GHz is the biggest signal frequency). Is there any issue? Do I need to match the diodes? How, and how much?
Can you give me an example?
Thanks,

Best Regards,

Is there any issue?

Yes, regular z-diodes don't work at high MHZ or GHz frequencies.

The capacitance of the two diodes will be so high that they will act as a short for GHz frequencies.

Sorry.

This makes the situation complicated; Thank you very much, you've avoided me a lot of problems.
Since I saw a circuit which used diodes as envelope detectors for the RF frequencies signals, I thought that zeners would also be ok. Can you tell me what parameter to see to judge diodes?
Also, do you have some ideas to clip RF signals?
