HMC441LM1

Overview

The HMC441LM1 is a broadband GaAs PHEMT MMIC medium power amplifier operating from 7.0 to 15.5 GHz. It provides 11 dB of gain and delivers +21.5 dBm saturated output power at 27% Power Added Efficiency (PAE). The device features a single +5V supply with optional gate bias, offering 50-ohm matched input and output interfaces. Packaged in an 8-terminal leadless SMT LCC carrier measuring 2.5mm x 2.5mm, it supports surface mount installation across a temperature range of -40°C to +85°C.

Feature Summary

• Single +5V supply voltage requirement with optional gate bias
• 50-ohm matched input and output for direct integration

Applications

• Point-to-Point Radios
• Point-to-Multi-Point Radios
• VSAT Systems
• LO Driver for HMC Mixers
• Military Electronic Warfare and ECM

Procurement Notes

Verify the specific suffix LM1 against the official Analog Devices datasheet to confirm the 7.0–15.5 GHz frequency range and 11 dB gain specifications. Ensure the leadless LCC package dimensions match the 2.5mm x 2.5mm footprint requirements. Confirm RoHS compliance status and check for any specific handling instructions regarding the GaAs MMIC construction during assembly.

Selection Notes

Select this component when a medium power amplifier is required for C-band through Ku-band applications. The single-supply architecture simplifies biasing networks compared to multi-voltage alternatives. The 50-ohm matching eliminates external impedance transformation circuits. Consider the thermal performance within the specified -40°C to +85°C operational range for the intended environment.

Part Context

This part belongs to the Hittite Microwave (now Analog Devices) portfolio of GaAs PHEMT MMICs designed for high-frequency RF applications. It serves as a medium power stage within broader microwave system architectures. The family includes variants with different frequency ranges, such as the HMC441LC3B and HMC441LP3E, which cover distinct spectral bands while maintaining similar packaging and interface characteristics.

Replacement Considerations

Public confirmed substitutes include HMC441LC3B and HMC441LP3E. Verify that the alternative part number matches the specific frequency band and gain requirements of the design. Check pinout compatibility and thermal dissipation capabilities before substitution.
