You can buy very low power transverters from this German company.

Homebrewing is very difficult at this frequency--the frequency is too high for packaged devices, so one needs to use a wire bonder to directly attach tiny wires to semiconductor die. From what I've heard, only a fraction of people who learn to use a wire bonder are really good at it.

The frequency you mention, 47.42GHz, is outside the amateur band of 47.0 to 47.2GHz. If this is your intention, the FCC does allow very low power Part 15 unlicensed devices. The power limit appears to be 500 uV/meter at 3 meters.

But, Part 15 is a very complex set of rules, an expert may be able to find a different interpretation,

The FCC does grant Part 5 experimental licenses if you can show a need.
