RAK3172 Txmode currnt

[song]

I am asking a question because only the minimum is listed in the document.

RAK3172 minimum Txmode current was 87mA.(@ 20 dBm 868 Mhz)

Set the band with KR920 and
I would like to know the maximum current when used.

Hello Song,

EU868 has a max transmit power of 20 dBm. KR920 is limited to 14 dBm.
On a quick test, using KR920 with max transmit power of 14dBm and using a small 1.2dBi antenna, I am getting 72mA peak current.

If I change the antenna to a 2.3 dBi antenna, the peak current goes up to 88mA:

Thank you for quick response!!
