HMC308E

Overview

The HMC308E is a low-cost MESFET MMIC amplifier manufactured by Analog Devices. It operates from a single +3 to +5V supply and covers a frequency range of 0.8 to 3.8 GHz. The device features a power dissipation of 406 mW, an input return loss of 13 dB, and delivers 100mW output power. It is housed in a compact SOT-26 surface-mount package.

Feature Summary

• Utilizes MESFET MMIC technology for cost-effective performance
• Operates on a single voltage supply ranging from +3V to +5V
• Provides wideband amplification across the 0.8 to 3.8 GHz spectrum

Applications

• Wireless RF communication systems
• Radio frequency signal processing
• Microwave circuit integration

Procurement Notes

Verify the specific ordering suffix (e.g., TR) against the required packaging format. Confirm RoHS compliance status as indicated in official documentation. Ensure the selected variant matches the intended surface-mount application requirements before finalizing procurement.

Selection Notes

Select this component for applications requiring broad bandwidth coverage between 0.8 and 3.8 GHz. Consider the single-supply operation capability when designing power architectures. Evaluate the SOT-26 package constraints for PCB layout compatibility.

Part Context

This part belongs to the Hittite Microwave family, now integrated into Analog Devices. It serves as a general-purpose RF amplifier solution designed for high-volume wireless infrastructure and consumer electronics markets requiring reliable microwave performance.

Replacement Considerations

The HMC308 is the non-E version of this component. Verify if the 'E' suffix denotes specific environmental or manufacturing lot variations that impact interchangeability with standard versions.
