Hot-selling and scarce SKY77629-13 Hybrid architecture separate GSM WCDMA paths QFN spot stock

Product Descriptions

The SKY77629 is a hybrid, multimode multiband (MMMB) Power  Amplifier Module (PAM) that supports 2.5G and 3G/4G handsets  and operates efficiently in GSM, EGPRS, EDGE, WCDMA, and LTE  modes. The PAM consists of: a GSM 800 / EGSM 900 PA block, a  DCS1800 / PCS1900 PA block, separate WCDMA blocks operating  in low and high bands, a logic control block for multiple power  control levels, and band enable functions in both cellular and  UMTS. RF I/O ports are internally matched to 50 Ω to minimize  the number of external components. Extremely low leakage  current maximizes handset standby time. The InGaP/GaAs die and  passive components are mounted on a multi-layer laminate  substrate and the assembly encapsulated in plastic overmold.​
