HMC442LC3BTR

Overview

The HMC442LC3BTR is a GaAs PHEMT MMIC medium power amplifier from Analog Devices Inc., operating within the 17.5 GHz to 25.5 GHz frequency range. It delivers a typical gain of 13 dB and a P1dB output power of 22 dBm, with a noise figure of 9 dB. The device requires a 5 V supply and draws 84 mA of current. It is housed in a leadless 12-VFQFN exposed pad surface-mount package (12-SMT, 3x3 mm). The component is RoHS compliant and operates between -40 °C and 85 °C.

Feature Summary

• Utilizes GaAs PHEMT MMIC technology for efficient medium power amplification
• Operates across the K-band frequency spectrum from 17.5 GHz to 25.5 GHz
• Housed in a compact, leadless surface-mount package with an exposed thermal pad

Applications

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

Procurement Notes

Verify the specific suffix LC3BTR against the official Analog Devices datasheet to confirm pinout and electrical characteristics match the design requirements. Ensure the ordering part number corresponds to the tape-and-reel packaging format required by the assembly line. Confirm that the 12-pin VFQFN footprint aligns with the PCB layout specifications before finalizing procurement.

Selection Notes

Select this component when a medium power output is required in the 17.5–25.5 GHz band with moderate gain. The 13 dB gain and 22 dBm P1dB make it suitable for intermediate stages in RF chains. Consider the 5 V supply requirement and 84 mA current draw for power budget calculations. The exposed pad package necessitates proper thermal management on the PCB substrate to ensure reliable operation within the specified temperature range.

Part Context

This part belongs to the HMC442 family of GaAs PHEMT MMICs designed for high-frequency applications. It serves as a medium power amplifier solution for systems requiring operation in the upper K-band. The device integrates matching networks internally, simplifying circuit design compared to discrete solutions. It is manufactured using Analog Devices' proprietary GaAs process technology.

Replacement Considerations

Consult the official Analog Devices documentation for verified cross-reference part numbers. Do not assume functional equivalence with other manufacturers' components without verifying pin compatibility and electrical parameters.
