I’m away from computer so only skimmed the article until I noticed they use the ADG90x RF switch family.
IIRC that family has a single positive supply rail, and they make a nagative rail internally. The advantage is easy of implementation but you also inject some noise depending on switch position. Is this dealt with in the pub?
