HMC383-SX

Overview

The HMC383-SX is a GaAs PHEMT MMIC medium power amplifier designed for VSAT and general-purpose RF applications. It operates within a frequency range of 12 GHz to 30 GHz. The device requires a single 5 V supply voltage and draws approximately 100 mA to 101 mA of current. Key electrical specifications include a typical gain of 15 dB to 17 dB, a noise figure ranging from 7.5 dB to 9 dB, and a saturated output power (P1dB) between 16 dBm and 16.5 dBm. The component is supplied in a die package format.

Feature Summary

• Utilizes GaAs PHEMT technology for high-performance amplification
• Designed as a medium power amplifier suitable for driver stages
• Operates across the Ku-band and Ka-band frequency spectrum

Applications

• VSAT communication systems
• RF signal chain driver stages
• General purpose microwave amplification

Procurement Notes

Verify availability status carefully, as this component may be subject to limited supply or discontinuation by Analog Devices Inc. Confirm the specific suffix requirements for your design, as packaging variations exist. Ensure compatibility with existing board layouts when sourcing replacements due to potential changes in manufacturing sources or lifecycle status.

Selection Notes

Select this component for designs requiring moderate output power in the 12-30 GHz range. Consider the 5 V supply requirement and thermal management needs associated with die-level packages. Evaluate the trade-off between the 7.5-9 dB noise figure and the 15-17 dB gain against system link budget requirements. Verify interface matching networks for optimal performance at target frequencies.
