That would be the first time i hear that. I was much rather believing the
1n400x is a slow rectifier diode.
Using the bias of a diode to switch rf does not require a fast diode, if
you don't need to switch fast.

I would like to know where you got that information, and maybe you should
look at the datasheets again.
