i want to ask about doublers put in series. After each doubler stage there is a filter pass for 2f. What if we do not filter in some stages? at very high ghz frequency it is possible to put bandpass or lambda/4 at f at 2f output. But at lower frequencies i do not like the mess with smd filters or giant bandpass hairpins. so what happens when few filters will gone away, and only two final stages have ones?
