HMC564

Overview

The HMC564LC4 is a low-noise amplifier IC from Analog Devices Inc., designed for RF applications in the 6GHz to 14GHz frequency range. It utilizes GaAs pHEMT MMIC technology and operates on a single 3V supply with a typical current consumption of 75mA. The device provides a small signal gain of 17dB, a noise figure of 1.8dB, and an output IP3 of 25dBm. It features a P1dB of 13dBm and is housed in a compact 24-lead QFN (4x4mm) surface-mount package.

Feature Summary

• Utilizes GaAs pHEMT MMIC technology for high performance and stability
• Operates on a single 3V power supply without requiring external matching circuits
• Provides low noise figure and high linearity for sensitive receiver front-ends
• Compact lead-free SMT package suitable for automated assembly

Applications

• Military communication systems
• Aviation radar and navigation equipment
• Microwave radio links
• Industrial test and measurement instruments
• Medical imaging devices

Procurement Notes

Verify the specific suffix (e.g., LC4) against the official datasheet to ensure correct package type and pinout compatibility. Confirm RoHS compliance status and moisture sensitivity level requirements for your manufacturing process. Check for any product change notifications that may affect electrical parameters or physical dimensions before finalizing procurement orders.

Selection Notes

Select this component when designing systems operating between 6GHz and 14GHz that require minimal noise addition and high linearity. The integrated design eliminates the need for external matching networks, simplifying schematic layout. Ensure the application can accommodate the 75mA supply current and that the thermal properties of the 4x4mm QFN package are sufficient for the expected power dissipation in the target environment.

Part Context

The HMC564 series represents Analog Devices' solution for high-frequency LNA needs, often paired with the HMC565LC5 for broader 6-20GHz coverage. Both devices share similar architectural benefits, focusing on ease of integration and robust performance in demanding RF environments. They are part of a broader portfolio of microwave components aimed at reducing system complexity while maintaining signal integrity across wide bandwidths.

Replacement Considerations

HMC565LC5 offers wider frequency coverage (6-20GHz) but different gain and noise characteristics. Verify if the extended bandwidth and slightly higher noise figure meet the specific link budget requirements of the design before substituting.
