low-pass filter in RFID 13.56MHz

[tok47]

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.
