I am analyzing a cell phone circuit and encountered these two ICs which I have not been able to identify, not even the chip manufacturer. Does the IC logo look familiar to anyone on this forum? thanks. 161121194130492.jpg161121195015420.jpg
 

Hi,

Skyworks looks like a good match for the manufacturer.

SKY77643-11 is described as a "Multimode Multiband Power Amplifier Module"

Skyworks web

The 77912-11 seems harder to trace, but there seems to be more for 77912-21, apparently somewhere in this large list.

Google search result #10 for skyworks 77912 ic says: "SKY77912-21, Tx-Rx Front-End Module for Quad-Band GSM / GPRS / EDGE w/ 10 Linear TRx ..."

Hope it's of use.
