HMC564LC4TR

Overview

The HMC564LC4TR is a general-purpose RF amplifier IC from Analog Devices Inc., designed for operation within the 6 GHz to 14 GHz frequency range. It utilizes Si technology and is housed in a 24-TFQFN (4x4 mm) package with exposed pad. The device operates on a supply voltage of 2.5 V to 3.5 V, drawing a typical supply current of 75 mA. Key electrical specifications include a gain of 17 dB, a noise figure of 1.8 dB, and a P1dB compression point of 13 dBm. This component is suitable for applications requiring low noise amplification in wireless systems.

Feature Summary

• Provides high gain and low noise performance across a wide microwave frequency band
• Utilizes surface-mount QFN packaging for compact circuit integration
• Operates efficiently with standard single DC supply voltages

Applications

• GPS receiver front-end amplification
• Wireless communication system signal chains
• Microwave test and measurement equipment

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Check for recent Product Change Notifications (PCN) regarding manufacturing site or material updates. Ensure proper ESD handling procedures are followed during storage and installation.

Selection Notes

Select this amplifier when a balance of moderate gain and very low noise figure is required in the 6-14 GHz range. Consider the 24-QFN footprint for PCB space constraints. Evaluate thermal dissipation requirements based on the 75 mA supply current. Compare against GaAs alternatives if higher power handling or different frequency ranges are needed.

Part Context

This part belongs to the HMC564 series of RF amplifiers by Analog Devices. It is functionally similar to the HMC564LC4 but differs in packaging format. The TR suffix indicates tape-and-reel packaging, distinct from the cut-tape or bulk options available for other variants in the same family.

Replacement Considerations

Direct substitutes may include HMC564LC4 for non-reel packaging needs. Verify pin compatibility and electrical parameters before swapping. No official cross-reference list is provided; engineering validation is required for any alternative component.
