HMC441LP3E

Overview

The HMC441LP3E is a broadband GaAs pHEMT MMIC medium power amplifier operating between 6.5 and 13.5 GHz. It features a typical gain of 13 dB and a noise figure of 4.75 dB. The device operates on a 5 V supply with a current draw of 90 mA to 115 mA. Key performance metrics include a P1dB compression point of 17 dBm to 18 dBm, an OIP3 of 29 dBm, and an input return loss of 15 dB. It is housed in a leadless plastic QFN-16 (3x3 mm) surface-mount package.

• Broadband operation across the 6.5 to 13.5 GHz frequency range using GaAs pHEMT technology
• Integrated optional gate bias for precise adjustment of output power and linearity
• High linearity and low noise characteristics suitable for sensitive RF applications
• Compact leadless plastic QFN surface-mount package design

Applications

• Point-to-Point Radios
• Point-to-Multi-Point Radios
• VSAT systems
• LO Driver for HMC Mixers
• Military EW & ECM

Procurement Notes

Verify the specific suffix (e.g., E for RoHS compliance) against the manufacturer's latest documentation to ensure correct material composition. Confirm that the required supply voltage and biasing conditions align with the system design, particularly regarding the optional gate bias functionality. Ensure the QFN-16 footprint matches the PCB layout specifications exactly.

Selection Notes

Select this component when a wide bandwidth covering C-band through Ku-band is required in a compact form factor. The integrated gate bias feature allows for optimization of the trade-off between output power and linearity without external complex circuitry. Consider the thermal dissipation requirements associated with the small QFN package during high-power operation.

Part Context

This part belongs to the HMC441 series of medium power amplifiers from Analog Devices. It utilizes Gallium Arsenide pHEMT monolithic microwave integrated circuit technology to deliver consistent performance across a broad frequency spectrum. The series is designed for applications requiring reliable RF signal amplification in space-constrained environments.

Replacement Considerations

Check for direct pin-compatible substitutes within the same family or newer revisions. Verify if alternative packages offer improved thermal performance while maintaining identical electrical specifications for the target application.
