Achim of course I am using Filters, among others the wide band inductors Radio Conrad offers. Contact me direct and I will send you sketches of what I do, including GPSDO with 10811. Where are you located? Bert In a message dated 2/13/2011 8:44:56 A.M. Eastern Standard Time, avoll...@physik.uzh.ch writes:
Dear Bert and all, maybe I missed it, but how can a linear regulator filter out transients from a switched PSU? The cited LT1764A has less than 30dB Suppression at 100 kHz getting worse for higher frequencies.Even the famous 7805 had only 50 dB suppression. For going to a real clean PSU, I would expect some old-school filtering and screening should be fine.. or am I wrong? A classic 50/60 Hz all linear PSU has a bad efficiency, but very little high frequency spurs to care about. For my current project (GPSDO with double oven HP10811), I will only use those.. even the classic LED 7-segment display I am planning to use will not use multiplexed mode but quasi-static (1 Hz update rate only).
