HMC6147ALC5A

Overview

The HMC6147ALC5A is a GaAs MMIC I/Q downconverter operating in the 37 GHz to 44 GHz RF range. It features a low noise amplifier driving an I/Q mixer, with LO input driven by a x2 multiplier covering 16.5 GHz to 22 GHz. The device provides 13 dB small signal conversion gain and a 3.5 dB noise figure. It operates on a single 3 V supply with currents of 75 mA and 150 mA. Packaged in a leadless QFN-EP-16 SMT format, it supports IF frequencies from 0 Hz to 4 GHz.

Feature Summary

• Integrates a low noise amplifier and I/Q mixer for direct frequency conversion
• Includes an internal x2 multiplier for local oscillator drive
• Provides dual IF outputs (IF1 and IF2) for balanced processing

Applications

• Radar systems
• Point-to-point communication links
• Electronic warfare applications

Procurement Notes

Verify the specific suffix (e.g., LC5A vs LC5ATR-R5) against the official Analog Devices datasheet to ensure correct packaging and reel specifications. Confirm RoHS compliance status and moisture sensitivity levels prior to assembly. Cross-reference the manufacturer part number with authorized distributors to validate current availability and authenticity.

Selection Notes

Select this component when a compact, high-frequency downconversion solution is required for millimeter-wave bands. Ensure the system design accommodates the 3 V single-supply requirement and the specified thermal dissipation limits. Verify that the external LO source matches the 16.5–22 GHz input range compatible with the internal x2 multiplier.

Part Context

This device belongs to the HMC6147A series of wireless and RF integrated circuits. It is manufactured using Gallium Arsenide (GaAs) technology. The component is designed for surface-mount installation in leadless packages, targeting high-performance applications in the 37–44 GHz spectrum.

Replacement Considerations

Consult the official Analog Devices documentation for verified substitute part numbers within the same family or functional equivalents.
