HMC442LM1

Overview

The HMC442LM1 is a broadband GaAs PHEMT MMIC medium power amplifier designed for operation between 17.5 GHz and 24 GHz. It features a gain of 13 dB, a noise figure of 8 dB, and an input return loss of 10 dB. The device operates on a 5 V supply with a current draw of 84 mA. Key performance metrics include a P1dB compression point of 22 dBm and an OIP3 of 26 dBm. It is housed in an SMT leadless chip carrier package (QFN-12) suitable for surface mount applications.

Feature Summary

• Utilizes GaAs PHEMT MMIC technology for high-frequency performance
• Provides true surface mount broadband millimeter-wave packaging
• Ensures low signal loss and excellent I/O matching characteristics

Applications

• Point-to-point radio systems
• Wireless local loop infrastructure
• Satellite communication terminals

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm exact frequency range and package variant. Ensure compatibility with 5 V supply requirements and thermal management needs for the QFN-12 footprint. Confirm moisture sensitivity handling procedures are followed during assembly to maintain component integrity.

Selection Notes

Select this component when a compact, broadband medium power amplifier is required for K-band applications. Consider the trade-off between the 13 dB gain and 8 dB noise figure relative to system link budget requirements. Evaluate the 22 dBm output power capability against load impedance conditions to ensure stable operation within the specified temperature range.

Part Context

This part belongs to the HMC442 series of medium power amplifiers from Analog Devices. It shares similar architectural foundations with variants like the HMC442LC3B but differs in specific frequency coverage and package type. The LM1 variant specifically targets the 17.5 to 24 GHz band using a leadless chip carrier format.
