HMC311ST89E

Overview

The HMC311ST89E is a GaAs InGaP HBT gain block MMIC amplifier from Analog Devices Inc., operating from DC to 6 GHz. Packaged in an SOT-89E, it delivers 16 dB of gain with a noise figure of 5 dB. The device requires a 5 V supply and draws 55 mA. Key performance metrics include a P1dB of 15.5 dBm, an OIP3 of 31.5 dBm, and an input return loss of 14 dB. It functions as a general-purpose RF amplifier suitable for wideband applications within the specified frequency range.

Feature Summary

• Utilizes GaAs InGaP Heterojunction Bipolar Transistor (HBT) technology for high-performance amplification
• Provides broadband operation covering DC to 6 GHz frequency range
• Features low power consumption with a 5 V supply requirement
• Designed in a compact SMT SOT-89E package for surface mount integration

Applications

• General purpose RF amplification circuits
• Wideband communication systems
• Test and measurement equipment front ends

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm the specific suffix 'E' denotes the correct package variant. Check lifecycle status as sources indicate this model may be obsolete. Ensure technical specifications align with current design requirements before procurement.

Selection Notes

Select this component for applications requiring a wide bandwidth up to 6 GHz with moderate gain. Consider the SOT-89E package constraints for PCB layout. Evaluate thermal management needs given the 340 mW power dissipation. Compare against newer alternatives if long-term availability is critical due to potential obsolescence.

Part Context

This part belongs to the HMC311 series of gain block amplifiers. It is distinct from evaluation boards like the HMC311ST89. The 'E' suffix typically indicates the specific SOT-89E package configuration. It serves as a discrete active component rather than a development tool.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with direct replacements by comparing electrical parameters such as gain, noise figure, and pinout configurations.
