HMC490

Overview

The HMC490 is a high dynamic range GaAs PHEMT MMIC Low Noise Amplifier operating between 12 and 17 GHz. It provides 27 dB of gain, 2 dB noise figure, and 35 dBm output IP3 at +5V supply voltage. The device features 50-ohm input and output matching for easy integration into RF systems.

Feature Summary

• High dynamic range performance with low noise figure
• GaAs PHEMT MMIC technology for reliable operation
• Integrated 50-ohm input and output matching

Applications

• Point-to-point radio systems
• Point-to-multipoint radio systems
• VSAT (Very Small Aperture Terminal) applications
• Military and aerospace communications

Procurement Notes

Verify current availability status as the component may be subject to limited supply or discontinuation. Confirm package type requirements, as the HMC490 is available in die form which requires specific handling and integration considerations during procurement and assembly processes.

Selection Notes

Select this component for applications requiring high linearity and low noise in the K-band frequency range. Ensure system design accommodates the +5V supply requirement and thermal management needs given the power dissipation characteristics of the GaAs PHEMT technology used in this amplifier.

Part Context

The HMC490 belongs to Analog Devices' portfolio of RF amplifiers designed for wireless communication systems. As a monolithic microwave integrated circuit (MMIC), it offers compact size and high performance suitable for space-constrained applications in satellite and terrestrial radio links.
