HMC441LH5

Overview

The HMC441LH5 is a broadband GaAs PHEMT MMIC medium power amplifier designed for operation between 7 GHz and 15.5 GHz. It delivers 15 dB of gain with a noise figure of 4.75 dB. The device operates on a 5 V supply, drawing 90 mA of current. Key performance metrics include a saturated output power of 21.5 dBm at 25% PAE, a P1dB compression point of 19 dBm, and an OIP3 of approximately 29 dBm. It is housed in a hermetic 12-CSMT (5x5) surface-mount leadless package suitable for high-reliability applications.

Feature Summary

• Utilizes GaAs PHEMT technology for robust RF performance
• Features a hermetic SMT leadless package for environmental sealing
• Provides wideband amplification across the 7 to 15.5 GHz spectrum
• Designed as a general-purpose medium power amplifier

Applications

• GPS and satellite navigation systems
• Point-to-point microwave radio links
• Electronic warfare and signal intelligence equipment
• Test and measurement instrumentation

Procurement Notes

Verify the specific suffix and packaging configuration when ordering, as Analog Devices offers various tape-and-reel options for this component. Confirm that the hermetic seal requirement aligns with your system's environmental specifications. Ensure compatibility with the 12-CSMT footprint during PCB layout. Check for any recent updates to the datasheet regarding electrical characteristics or recommended operating conditions before finalizing the bill of materials.

Selection Notes

Select the HMC441LH5 when a hermetically sealed medium power amplifier is required for frequencies up to 15.5 GHz. It is appropriate for designs needing 15 dB of gain with moderate output power capabilities. Consider this part over non-hermetic variants if long-term reliability in harsh environments is critical. Evaluate the 5 V supply constraint against your system's power budget.
