HMC374SC70E

Overview

The HMC374SC70E is a general-purpose broadband Low Noise Amplifier (LNA) designed for the 0.3 to 3 GHz frequency range. Manufactured using GaAs pHEMT technology, it delivers a typical gain of 15 dB with a noise figure of 1.6 dB. The device operates on a supply voltage between 3 V and 3.6 V, drawing a typical current of 75 mA. Key performance metrics include an output P1dB of 17 dBm and an OIP3 of 28 dBm. It is housed in a compact SC-70-6 surface-mount package, suitable for space-constrained RF applications.

Feature Summary

• Broadband operation across 0.3 to 3 GHz utilizing GaAs pHEMT MMIC technology
• Low noise figure of 1.6 dB combined with high linearity for signal integrity
• Compact SC-70-6 surface-mount package for minimal footprint

Applications

• GPS receiver front-ends
• Wireless LAN infrastructure
• General purpose RF signal conditioning

Procurement Notes

Verify the specific suffix 'E' against official Analog Devices documentation to confirm lead-free compliance status. Ensure the SC-70-6 package variant matches the required PCB layout. Cross-reference the datasheet revision date to confirm parameter validity. Confirm availability through authorized distributors as standard delivery times may vary. Validate that the operating voltage range aligns with the system power design.

Selection Notes

Select this component when a low-noise solution is required for frequencies up to 3 GHz. The 15 dB gain and 1.6 dB noise figure make it suitable for sensitive receiver chains. Consider the SC-70-6 package size if board real estate is limited. Compare the 17 dBm P1dB against system linearity requirements. Evaluate the 75 mA supply current against power budget constraints.

Part Context

This part belongs to the HMC374 series of low noise amplifiers from Analog Devices. It represents a specific package variant (SC-70-6) of the broader HMC374 family. The series utilizes GaAs pHEMT technology for high performance. Other variants may exist in different packages such as SOT-23-6. The HMC374SC70E is distinct from higher frequency or power amplifier models in the same catalog.
