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.
