Ugreen AC1300 WiFi Stick Amplifiers

Hi Guys!
I´m still new to openHD and did some bench testing including the ugreen ac1300 WiFi stick, that uses the rtl8812au chip. It works without any problems (on the bench). I opened up the case, mainly to see if i could connect external antennas and to see the chips used.

Here is a picture of the pcb. The two small chips look like some sort of rf amps, but i couldn´t find any info on them. They say 977 633C K102 on them. Maybe someone knows this card or the chips used and could suggest a power level save to use.
