TRF7960A: How much power can you transfer across an NFC link?

Part Number: TRF7960A
Other Parts Discussed in Thread: RF430CL330H

Hi , In this application the coils would be fixed in situ relative to each other,  I have seen that competitor claims 10mA at 2V in a harvesting situation. Is this practical and do we have any reference material that can support this?

    Hello ajayt,

    RF field on a typical TRF7960A application can provide approx. 1mA of current for circuits operating at 3V such as our RF430CL330H.

    The power claim they make isn't unheard of, but would require an external power amplifier to achieve with our devices. However, we do not support any external power amplifiers.
