www.DataSheet4U.com PRODUCT SUMMARY SKY77441 Multi-Mode / Multi-Band PA Module for LTE FDD Band VII (2500–2570 MHz) and LTE TDD Bands 38 / 40 (2300–2620 MHz) APPLICATIONS Long-Term Evolution (LTE) FDD and TDD Evolved Universal Terrestrial Radio Access Networks (EUTRAN) Handsets and Data Cards The SKY77441 Power Amplifier Module (PAM) is a fully matched, surface mount module developed for LTE / EUTRAN FDD and TDD applications. This small and efficient module packs full coverage of LTE FDD Band VII and LTE FDD Bands 38 / 40 into a single compact package, and is capable of delivering the linear WCDMA power up to 28.5 dBm from 2.3 to 2.7 GHz. The SKY77441 meets the stringent spectral linearity requirements of LTE modulation with QPSK / 16QAM modulations from 1.4 MHz 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 the 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 SKY77441 is supplied via the VCC1 and VCC2 p...
