Applications

• VSAT satellite communication systems
• DBS direct broadcast satellite receivers
• Point-to-point microwave radio links

Procurement Notes

Verify component authenticity through authorized Analog Devices channels due to limited availability status. Confirm that the die package matches specific board layout requirements. Ensure thermal management solutions accommodate the specified power dissipation limits during continuous operation in high-temperature environments.

Selection Notes

Select this component when high linearity and low noise are critical within the 12 to 17 GHz band. Consider the die form factor for custom hybrid or monolithic integration. Evaluate the 5V supply requirement against system power constraints. Compare against other LNA options if broader frequency coverage or different packaging formats are required.

Part Context

This part belongs to the HMC490 series of RF amplifiers from Analog Devices. It is specifically engineered for Ku-band applications requiring high dynamic range. The SX suffix indicates a sample or specific die configuration distinct from standard packaged variants, targeting specialized integration needs.
