Under the hood, he found a PIC microcontroller and a MAX2870 frequency synthesizer, but a conspicuous absence of any RF filtering components, which explains how the output got so crusty.

A design of voltage doubler circuit ... the final voltage transferred to C2 without output load is equal to 2VRF,max. Furthermore, it is easy to determine that the output voltage of such n-stage ...

The compact design ... RF Vector Signal Generator can also operate within automated test system designs as a signal source module, simulating many different RF systems for analysis. With output ...
