i have 400w switching power supply,but i have a problem of the noise around 100khz and 300khz
pleas if you have any solution for that problem to move this switchin frequencies to moor the 4 Mhz .
thanks you
thank you very much for your response.
to be moor specified, this switching power supply used for radar system delivering 24 v ,10 A.
i would like you to help me to find the right filter that can filter all frequencies less the 500 mhz.
thanks you

For radar system, I think there should be some synchronisation between the switching frequency and pulse repetition frequency, such that you don't see the power supply switching spurii in the transmitter spectrum. Any microwave TWTA books will discuss about power supply synchronisation circuit.
