We do have several customer building RF amplifiers and they often ask what is the switching frequency that our supplies operate and chose one accordinglyUnknownhttps://www.blogger.com/profile/03069078041791854605noreply@blogger.comtag:blogger.com,1999:blog-535177224836915617.post-26121301652457638922010-10-27T09:17:54.466-07:002010-10-27T09:17:54.466-07:00OK, can we talk about ripple?

Right now I'm using a linear supply with 1 mV of ripple and 0.05% line and load regulation. I could use switchers, but then the redesign would start all over again.Unknownhttps://www.blogger.com/profile/12234658255516141451noreply@blogger.com
