13.56mhz amplifier
HI!
I'm designing a RFID reader using ISO15693 protocol at 13.56MHz using TI S4100 module. This reader unit would have an output power of about 200mW. I'm using a 50 ohm matched loop antenna with 50cmX50cm dimensions. Up to now a range of about 25-30cm was achieved.
I want to increase the range to about 70cm or more. For that i need to use a suitable power amplifier. Can any body help me with some suitable design for this.
Specifications for the amp
13.56MHz operation.
Input impedance - 50Ω
Output impedance- 50Ω
Output power ≥ 1W
Thanx a lot,
Amila
