HMC463-SX

Overview

The HMC463-SX is a GaAs PHEMT MMIC low noise amplifier with automatic gain control, designed for broadband applications from 2 GHz to 20 GHz. It provides 14 dB typical gain and operates on a single 5 V supply drawing 60 mA. The device features a noise figure of 3 dB, input return loss of 15 dB, P1dB compression point of 19 dBm, and OIP3 of 30 dBm. It is housed in a QFN-32 package suitable for surface mount installation.

Feature Summary

• Integrates automatic gain control for stable signal amplification across wide bandwidths
• Utilizes GaAs PHEMT technology for high-performance RF processing
• Designed as a general-purpose low noise amplifier for GPS and broadband systems

Applications

• GPS receiver front ends
• Broadband communication systems
• Test and measurement instrumentation

Procurement Notes

Verify the specific suffix designation against official Analog Devices documentation to confirm the die variant status. Ensure compatibility with existing board layouts and thermal management requirements for the QFN-32 form factor. Cross-reference the manufacturer part number with authorized distributors to confirm current availability and lead times.

Selection Notes

Select this component when a wide frequency range up to 20 GHz is required alongside integrated gain control capabilities. Consider the 5 V supply requirement and 60 mA current consumption during power budgeting. Evaluate the 3 dB noise figure against system sensitivity needs and verify that the 19 dBm P1dB meets linearity requirements for the intended application environment.

Part Context

This component belongs to the HMC463 series of low noise amplifiers manufactured by Analog Devices Inc. It represents a monolithic microwave integrated circuit (MMIC) solution utilizing Gallium Arsenide PHEMT technology. The SX suffix typically denotes a specific die configuration within the product family, distinct from packaged variants like the LP5E.
