It features integrated bypass mode functionality, making it suitable for fixed wireless applications. The device operates on a +3V supply with a current consumption of 9 mA. Key electrical specifications include a gain of 16 dB, a noise figure of 2 dB, and an input IP3 of +3 dBm. It is housed in a compact QFN package.

Feature Summary

• Integrated bypass mode for versatile signal routing
• Low power consumption optimized for portable systems
• High linearity with +3 dBm input IP3

Applications

• Fixed Wireless Access (FWA)
• Point-to-Point Microwave Links
• Wireless Local Loop Systems

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm the specific datasheet revision matches your design requirements. Ensure proper ESD handling procedures are followed during storage and assembly due to the sensitive GaAs MMIC nature of the device.

Selection Notes

Select this component when low noise performance and high linearity are required in the 3.4–3.8 GHz band. The integrated bypass feature simplifies system architecture by eliminating external switching components. Consider the 9 mA supply current for battery-operated designs requiring efficient power management without compromising RF performance.

Part Context

This part belongs to the HMC491 family of LNAs. It is specifically engineered for C-band and lower microwave applications. The LP3E suffix indicates the lead-free RoHS-compliant version in a QFN package. It complements other RF front-end components in wireless infrastructure equipment.

Replacement Considerations

Check for direct pin-compatible alternatives within the Analog Devices portfolio that meet identical frequency and gain specifications. Verify if updated revisions offer improved thermal characteristics or packaging options while maintaining functional equivalence.
