HMC8108LC5TR

Overview

The HMC8108LC5TR is a GaAs MMIC up/down converter operating in the 9 GHz to 10 GHz X-band range. It functions as a low noise converter (LNC) with integrated I/Q demodulation capabilities. The device provides a gain of 13 dB and achieves a noise figure of 2 dB. Key linearity metrics include a P1dB compression point of -4 dBm and an OIP3 of 6 dBm. It operates on a single 3 V supply, drawing 40 mA of current. The component is housed in a CLCC-32 surface-mount package.

Feature Summary

• Integrates low noise amplification with direct I/Q downconversion for simplified receiver architectures
• Utilizes GaAs MMIC technology to ensure high performance across the X-band frequency spectrum
• Designed for single-supply operation to reduce system power complexity

Applications

• X-band radar systems requiring compact receiver front-ends
• Satellite communication ground stations
• Electronic warfare signal intelligence receivers

Procurement Notes

Verify the specific suffix 'R5' against your bill of materials, as it denotes reel packaging. Confirm RoHS compliance status through official Analog Devices documentation prior to integration. Ensure the CLCC-32 footprint matches your PCB layout constraints. Cross-reference the datasheet revision date to confirm parameter stability for your design lifecycle.

Selection Notes

Select this component when designing X-band receivers that require integrated LNA and mixer stages to minimize board space. The 2 dB noise figure is critical for weak signal detection applications. Verify that the 13 dB gain meets your link budget requirements without excessive external amplification. Consider the 3 V supply constraint if your system architecture differs from standard 5 V designs.

Part Context

This part belongs to the HMC8108 series of X-band converters manufactured by Analog Devices. It is distinct from higher-frequency models like the HMC819 or different-package variants within the same family. The device represents a specialized solution for narrowband X-band applications rather than wideband general-purpose conversion.

Replacement Considerations
