RF measurements: for frequencies greater than 6GHz

Hi,

I am finding that most signal generators are in the range of less than 6GHz measurement. They are pretty cheap also.Similar applies to VNAs, Spectrum analyzers.

Is there any way to get a non-conventional solution around how I can use these lower frequency range equipments and yet utilize them for higher frequencies?

Very open to any ideas on how this can be done. Most welcome to clarify this application requirement in case of any specific queries.

Additinally, I would like to know the real technical reason why there is so much of a price difference in 6GHz equipments and measurement devices that are at peak measurement frequencies of 8GHz. There seems to be an almost standard 6GHz cut-off for a lot of equipment I see around.

Cost with scale factor for features will be Sk/GHz due to complexity of RF and material design quality.


I have seen S250k Generators. ! and S250 gens. This is normal.

/details are in the specs/

The main reason is hardware complexity and so far the production remained in low numbers. As the instruments become more common, the cost can go down.
One can use up- and down converters to extend frequency range above 6 GHz. Some companies work up to 110 GHz, others even in THz range.
