HMC374E

Overview

The HMC374E is a surface-mount PHEMT low noise amplifier designed for the 0.3 to 3.0 GHz frequency range. It delivers 15 dB of gain with a typical noise figure of 1.5 dB. The device operates from a single positive supply voltage of 5 V, drawing 90 mA of current. Key performance metrics include a 1 dB compression point (P1dB) of 22 dBm and a third-order intercept point (OIP3) of 37 dBm. It features an input return loss of 13 dB and dissipates 488 mW of power. The component is housed in a compact SOT-23-6 package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• General-purpose broadband low noise amplification across 0.3 to 3.0 GHz
• High linearity with 37 dBm OIP3 and 22 dBm P1dB
• Low noise figure of 1.5 dB for sensitive signal reception
• Single 5V positive supply operation

Applications

• GPS receiver front ends
• Wireless communication systems
• Test and measurement equipment

Procurement Notes

Verify availability status carefully as distribution channels may list this part as limited or discontinued. Confirm the specific suffix 'E' matches the required SOT-23-6 package variant. Check RoHS compliance details against current regulatory requirements. Ensure the supplier provides official Analog Devices documentation to validate authenticity and technical specifications before procurement.

Selection Notes

Select the HMC374E when a broad bandwidth covering 0.3 to 3.0 GHz is required alongside low noise performance. It is suitable for applications needing high linearity (37 dBm OIP3) in a small SOT-23-6 footprint. Consider the 5V supply requirement and 90mA current draw for power budgeting. Compare against the HMC374SC70ETR if a smaller SC-70-6 package is preferred, noting differences in supply voltage and packaging.

Part Context

The HMC374E belongs to the HMC374 family of general-purpose broadband LNAs from Analog Devices. It utilizes PHEMT technology to achieve high performance in a compact surface-mount format. The 'E' suffix typically denotes the specific SOT-23-6 package variant. This series is engineered for cost-effective integration into RF front-end modules requiring wideband coverage.

Replacement Considerations

HMC374SC70ETR is listed as a similar alternative by distributors, though it uses an SC-70-6 package and different supply voltage.
