www.DataSheet4U.com PRODUCT SUMMARY SKY77449 Power Amplifier Module for LTE / EUTRAN Bands XIII / XIV (777–798 MHz) APPLICATIONS Long-Term Evolution (LTE) Evolved Universal Terrestrial Radio Access Networks (EUTRAN) Handsets and Data Cards The SKY77449 Power Amplifier Module (PAM) is a fully matched, surface mount module developed for LTE / EUTRAN applications. This small and efficient module packs full coverage of Bands XIII / XIV LTE / EUTRAN / WCDMA into a single compact package. The SKY77449 meets the stringent spectral linearity requirements of LTE modulation with QPSK / 16QAM modulations from 1.4 to 20 MHz bandwidth and full or partial resource block allocations with high power added efficiency. Integration of the PAM simplifies the design of the 4G-compatible handset radios and data cards as all active RF circuitry including the PA, input, interstage and output matching circuits, and power detector are optimized within the single module component. Output match is realized off-chip within the module package to optimize efficiency and power performance into a 50 Ω load. The device is manufactured with Skyworks’ BiFET process that provides for all positive voltage DC supply operation while maintaining high efficiency and good linearity. Primary bias to the SKY77449 is supplied via the VCC1 and VCC2 pads directly from a three-cell Ni-Cad, a single-cell Li-Ion, or other suitable battery with output in the 3.0 to 4.6 volt range, while the bias network is powered via ...
