Hello Josh,
The RF37S114 has the antenna included in the device packaging, and it is not meant to be used with larger antennas to increase the read range. This is a completed product to be used as is.
The die which was used to create the RF37S114…
do u mean, the TRF7970AEVM like saying can scan multiple tags per second based on the NFCLink? (like counting tags per second)
No, The TRF7970AEVM and TRF7960AEVM do not use the NFCLink software. They have their own firmware and it supports reading…

Hi Jerome,
This antenna should be ok as long as you are driving the TRF7960 with 5V in full power mode. I have used a 300mm x 300mm antenna from Feig Electronic with the TRF7960 succesfully. This is about the largest size you can go without an amplifier…

Athul -
your tags will be too small for an antenna of that size - for your reference some time back i had connected up our reader platform to Feig 300mm x 300mm antenna to check this exact scenario...the problem is basically a tag that small requires…
Hi Ethan,
The TRF7960EVM puts out 200mW. This is a low output power reader IC and would not properly drive a 3m loop antenna. I would suggest at least 1W output power to drive such an antenna and probably more like 4W-8W to acheive the 1m range. The…
