u2270b antenna
Hello everybody
I'm trying to design a Handheld RFID reader on the 125KHz using the U2270B from Atmel. I looked through the schematics provided by Atmel and they recommend an antenna coil with and inductance of 1.35-1.5mH, which seems a bit large for me.
I did a search in this website and the topic had came up in the past, but I can't download the information previously posted given the current rules of this site.
Could anybody,(hey Luben111, are you around), tell me if this value is correct or there is something wrong there?
Any feedback would be appreciated.
Thanks
Ed.
