HMC442LC3BTR

Overview

The HMC442LC3BTR is a medium power RF amplifier from Analog Devices (Hittite) operating in the 17.5 GHz to 25.5 GHz range. It features a typical power gain of 13 dB and a P1dB output of 22 dBm. The device has a noise figure of 9 dB and draws 84 mA from a single 5 V supply. Packaged in a 12-SMT (3x3 mm) VFQFN with exposed pad, it supports test frequencies between 21 GHz and 24 GHz.

Feature Summary

• Utilizes GaAs MMIC technology for high-frequency performance
• Operates on a single 5V power supply
• Compact 3x3 mm surface mount package

Applications

• Point-to-point radio links
• Military radar systems
• Instrumentation applications

Procurement Notes

Verify the manufacturer designation as Analog Devices Inc., noting the historical Hittite brand association. Confirm the specific suffix LC3BTR indicates the tape and reel packaging variant. Ensure compliance with RoHS3 standards and check the Moisture Sensitivity Level (MSL 3) requirements during storage and handling procedures.

Selection Notes

Select this component for designs requiring wideband amplification up to 25.5 GHz. The 13 dB gain and 22 dBm output power suit medium power applications. Consider the 12-pin QFN footprint for PCB layout constraints. Evaluate thermal management needs due to the exposed pad design and 84 mA current consumption at 5 V.

Part Context

This part belongs to the Hittite microwave amplifier family, now integrated into Analog Devices' portfolio. It serves as a solid-state solution for X-band and Ku-band frequencies. The device replaces older discrete transistor designs with a monolithic integrated circuit offering consistent performance and smaller form factors for modern communication systems.

Replacement Considerations

Direct substitutes are not explicitly confirmed in public documentation. Review the HMC441LC3B for lower frequency coverage or the HMC445LP4E if frequency multiplication is required instead of amplification. Verify pin compatibility and impedance matching before substitution.
