SKY77413-21

RF Front End (LNA + PA) Overview

The SKY77413-21 is a fixed-frequency RF front-end module designed for cellular W-CDMA applications. It operates within the 824MHz to 849MHz frequency range and integrates Low Noise Amplifier (LNA) and Power Amplifier (PA) functions. The component supports broadband, high-power, and high-linearity performance characteristics suitable for single-mode wireless communication systems.

RF Front End (LNA + PA) Feature Summary

• Integrates LNA and PA in a single module
• Optimized for high linearity and power output
• Designed for W-CDMA cellular standards

RF Front End (LNA + PA) Applications

• W-CDMA cellular handsets
• RF front-end modules for 3G devices
• Broadband wireless communication terminals

RF Front End (LNA + PA) Procurement Notes

Verify current availability status as the part may be discontinued or subject to limited supply conditions. Confirm package type and pinout compatibility with target PCB design before procurement. Ensure sourcing from authorized distributors to guarantee authenticity and traceability of the Skyworks Solutions Inc. component.

RF Front End (LNA + PA) Selection Notes

Select this component for legacy W-CDMA designs requiring integrated amplification without tunable matching. Note that unlike modern LTE/5G modules, this part is fixed-frequency and single-mode. Evaluate thermal management requirements due to high-power operation in the specified band.

RF Front End (LNA + PA) Part Context

The SKY77413-21 belongs to Skyworks' RF front-end circuit portfolio targeting third-generation mobile communications. It serves as a specialized solution for operators and device manufacturers deploying W-CDMA infrastructure and user equipment during the transition period between 2G and 4G technologies.

RF Front End (LNA + PA) Replacement Considerations

No public confirmed substitute part numbers are available. As a fixed-frequency, single-mode module, direct replacements must match the 824MHz-849MHz band and W-CDMA interface requirements exactly.
