HMC441

Overview

The HMC441 is a GaAs PHEMT MMIC medium power amplifier operating from 6 to 18 GHz. It provides 15.5 dB gain with a saturated output power of +22 dBm at 23% PAE. The device requires a single +5V supply and features 50-ohm matched input and output ports. Key electrical specifications include a noise figure of 4.5 dB, a P1dB compression point of 20 dBm, and an OIP3 of 32 dBm.

Feature Summary

• Broadband operation across the 6 to 18 GHz frequency range
• High efficiency performance with 23% Power Added Efficiency (PAE)
• Integrated 50-ohm input and output matching networks
• Single +5V power supply requirement for simplified biasing

Applications

• Point-to-Point Radios
• Point-to-Multi-Point Radios
• VSAT Systems
• Local Oscillator Drivers for Mixers
• Military Electronic Warfare and ECM

Procurement Notes

Verify component authenticity through authorized Analog Devices channels or certified distributors. Confirm that the specific package variant matches design requirements, as the HMC441 family includes die, LCC8, and LCQFN options. Ensure proper ESD handling protocols are followed during storage and assembly. Review current availability status, as supply constraints may affect lead times for this component.

Selection Notes

Select the HMC441 when broadband amplification between 6 and 18 GHz is required with moderate output power. Choose this part for applications needing high linearity and efficient power consumption under a single 5V supply. Consider alternative variants like the HMC441LM1 if the operational frequency range is limited to 7–15.5 GHz and a different package footprint is preferred for PCB layout constraints.

Part Context

The HMC441 belongs to the Hittite Microwave (now Analog Devices) portfolio of GaAs PHEMT monolithic microwave integrated circuits. These components are designed for high-performance RF and microwave systems requiring compact size and reliable operation. The HMC441 specifically targets medium power amplification needs in communication and defense electronics.
