energy efficiency on PN5180 board

[Thomas_jjzhou]

Hi, As I want to measure the energy efficiency on the PN5180 board. Could you provide the testing position of the VDD_RF pin on the PCB board and measure its current and voltage? And do you have a clear tutorial about your antenna auto-tuning system? Thanks

Thank you for using our products, we really appreciate this.

Please refer to our Evaluation board quick start guide (AN11744), where you will find in the Hardware section, about the pn5180 (2.2.3). The reference of the TVDD, which in the board is indicated as JP300.

In this paragraph, it is indicated that you can use an amperemeter in order to measure the current of the antenna.

I hope this may have been useful.
