HMC374SC70ETR

Overview

The HMC374SC70ETR is a surface-mount PHEMT low noise amplifier from Analog Devices Inc., designed for broadband applications between 300MHz and 3GHz. It operates on a single supply voltage of 3V to 3.6V with a typical current consumption of 75mA. Key electrical specifications include a gain of 15dB, a noise figure of 1.6dB, and an output P1dB of 17dBm. The device is housed in a compact SC-70-6 package, making it suitable for space-constrained RF front-end designs.

Feature Summary

• Utilizes PHEMT technology for high performance in a small form factor
• Provides broadband operation across the 300MHz to 3GHz frequency range
• Features low noise figure characteristics for sensitive signal reception
• Designed for single-supply operation to simplify power management

Applications

• GPS receiver front-ends
• Wireless LAN infrastructure
• Personal communication systems
• Broadband data terminals

Procurement Notes

Verify the specific suffix 'SC70ETR' confirms the SC-70-6 package and tape-and-reel packaging format. Ensure compatibility with the required 3V to 3.6V supply voltage range. Confirm that the 75mA supply current aligns with system power budget constraints. Check for RoHS compliance status if required by regional regulations. Validate pinout compatibility during PCB layout integration.

Selection Notes

Select this component when a low-noise, broadband amplifier is needed within the 300MHz to 3GHz spectrum. It is appropriate for designs requiring a 15dB gain with minimal noise contribution. Consider the SC-70-6 package size for tight board real estate limitations. Compare against other HMC374 variants if different supply voltages or packages are preferred. Ensure the 1.6dB noise figure meets the system's sensitivity requirements.

Part Context

This part belongs to the HMC374 family of SMT PHEMT low noise amplifiers. Other variants like HMC374ETR offer similar electrical performance but utilize an SOT-23-6 package. The family is characterized by broadband operation and low noise figures, targeting general-purpose RF applications. The SC70 variant specifically addresses miniaturization needs in modern wireless devices.

Replacement Considerations

HMC374ETR serves as a functional substitute with identical electrical specifications but uses an SOT-23-6 package instead of SC-70-6. Verify footprint compatibility before substitution. No other direct cross-model replacements are documented in the provided source material.
