Part Number: TRF7970A
Other Parts Discussed in Thread: TLIN1029-Q1,

Hi,

I'm doing a custom NFC reader board for asset tagging using MSP430F2370, TRF7970A and TLIN1029-Q1.

Want to confirm the schematics before doing the gerber, I'll send the schematics in private.

Also I want to achieve long range (atleast 10cm) reading capability, so is there any antenna reference for that ?

Hello Madhu,

I do not have a reference to a antenna for your needs. I can only point you to our Antenna Design Guide for the TRF7970A:

If you send you schematic I will have a look to it.

Best regards,
Helfried
