Good news.
I had rebuild the sampler with standard HSMS-8202 diode pair on FR4 pcb inside to the original case. I had increased the original hole to the diameter 10mm for easily assembling. I can accurately meassure up to 3GHz and the sensitivity in band 500MHz - 3Ghz is better than -30dB. Occasionally I will test higher frequencies...

Dear ivosak
Could you please share your designs detail or help me to build a sampler for my HP 5342A ?
I have the schematic but I don’t understand the balun circuit. Your experience will be very useful.
Thank you for your consideration.
