HMC1049-SX

Overview

The HMC1049-SX is a GaAs pHEMT MMIC low noise amplifier from Analog Devices Inc., operating between 300 MHz and 20 GHz. It provides 16 dB of small signal gain with a typical noise figure of 1.7 dB. The device requires a 7 V supply voltage and draws 70 mA of current. Key performance metrics include a P1dB compression point of 15 dBm and an OIP3 of 27 dBm. It features an input return loss of 13 dB and operates within a temperature range of -55°C to +85°C.

Feature Summary

• Utilizes GaAs pHEMT MMIC technology for high-performance RF amplification
• Provides wideband operation covering 300 MHz to 20 GHz
• Designed for low noise applications with minimal signal degradation

Applications

• VSAT communication systems
• Point-to-point microwave links
• Test and measurement equipment

Procurement Notes

Verify the specific suffix 'SX' against official Analog Devices documentation to confirm package type and tape/reel specifications, as standard HMC1049 variants may differ in packaging. Confirm availability status directly with authorized distributors, as supply constraints may apply to this component series.

Selection Notes

Select this component when a wideband LNA covering up to 20 GHz is required with moderate gain and low noise characteristics. Ensure the design accommodates the 7V supply requirement and thermal management for the specified power dissipation. Verify impedance matching networks are optimized for the target frequency band within the 300 MHz to 20 GHz range.

Part Context

The HMC1049 belongs to Analog Devices' portfolio of GaAs MMIC low noise amplifiers. It is part of a family designed for wireless infrastructure and satellite communications. The SX suffix typically denotes a specific packaging or testing configuration distinct from the bare die or standard QFN versions found in other listings.

Replacement Considerations

Publicly confirmed direct substitute part numbers for the HMC1049-SX variant are not available in the provided source data. Evaluate generic replacements like the HMC1049LP5E only if pinout and electrical parameters match the specific SX requirements.
