Other Parts Discussed in Thread: UCC27424-Q1, , TMS3705, UCC27424
Hi,
Good Day. I have a customer who has a query related to the E2E Forum Post.

Please see below his query for your reference. Thank you very much.
I reviewed the suggested links and from what I read I should use the IC TRF4140-Q1 as it should be able to work with FDX and HDX. Is there any option to increase it power and range? Maybe something like the IC UCC27424-Q1 which was used to increase the power in the driver stage of the antenna in combination with the TMS3705. The tag I'm trying to read is 3cm of diameter and the distance I need to achieve is 50 cm or more.
If the TRF4140 is the suitable, how can I increase it sensitivity for the detection of the signal? Maybe I can use an ARM4 MCU with DSP instruction to do some digital processing at some pin in the TRF4140 IC?
Best Regards,
Ray Vincent
