T tok47 New Member Apr 5, 2004 #1 Dear Frens, I'm now trying to design a low-pass filter that is a part of a RFID system. Beside, switch-current method, what other method that I can use? What the effect? Can anyone help me to deside a method?

I don't know what you mean by 'switch current method', an RF low pass filter would normally use coils and capacitors, at least one of each, depending on the roll-off you need.
