HMC442LM1TR

Overview

The HMC442LM1TR is a broadband GaAs PHEMT MMIC medium power amplifier designed for operation in the 17.5 to 24.0 GHz frequency range. It utilizes a surface-mount leadless chip carrier package, providing low loss and excellent input/output matching characteristics suitable for high-frequency applications.

Feature Summary

• Broadband amplification capability across the 17.5 to 24.0 GHz spectrum
• GaAs PHEMT MMIC technology for high-performance RF signal processing
• Surface-mount leadless chip carrier package design ensuring low insertion loss

Applications

• Point-to-point microwave radio links
• Satellite communication systems
• Electronic warfare equipment
• Radar subsystems

Procurement Notes

Verify the specific suffix (LM1 vs LC3B) against the required frequency band, as variants exist with different operational ranges. Confirm that the TR suffix indicates tape-and-reel packaging. Ensure compatibility with the intended PCB footprint and thermal management requirements before finalizing the order.

Selection Notes

Select this component when a fixed-gain medium power amplifier is needed specifically within the 17.5-24.0 GHz band. Consider the LM1 variant for standard broadband coverage. Evaluate thermal dissipation needs due to the MMIC nature and ensure the system impedance matches the amplifier's I/O characteristics.

Part Context

This part belongs to the HMC442 series of medium power amplifiers from Analog Devices. The series includes variants such as the HMC442LC3BTR which operates up to 25.5 GHz. The HMC442LM1TR specifically targets the lower end of the Ka-band spectrum using GaAs technology.

Replacement Considerations

The HMC442LC3BTR serves as a functional substitute if the application requires an extended upper frequency limit up to 25.5 GHz. Verify pinout compatibility and thermal specifications when cross-referencing these variants.
