HMC311ST89ETR

Overview

The HMC311ST89ETR is a GaAs InGaP HBT gain block MMIC amplifier operating from DC to 6 GHz. It provides 16 dB of gain with a noise figure of 5 dB. The device operates on a 5 V supply, drawing 55 mA. Key performance metrics include a P1dB of 15.5 dBm and an OIP3 of 31.5 dBm. Input return loss is 14 dB, and power dissipation is 340 mW. It is housed in an SOT-89-3 package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Utilizes GaAs InGaP Heterojunction Bipolar Transistor (HBT) technology for high-performance signal amplification.
• Designed as a general-purpose wideband low-power amplifier suitable for cascaded 50 Ohm applications.
• Integrated into a compact surface-mount SOT-89-3 package for efficient PCB integration.

Applications

• Wireless communication systems requiring broadband amplification
• Test and measurement equipment signal conditioning
• General-purpose RF front-end modules

Procurement Notes

Verify the specific suffix ETR against official Analog Devices documentation to confirm reel packaging and tape specifications. Ensure compatibility with SOT-89-3 footprint designs. Cross-reference the datasheet for exact electrical tolerances at target frequencies. Confirm RoHS compliance status through current manufacturer declarations. Validate that the component meets environmental operating ranges for the intended deployment scenario.

Selection Notes

Select this component when a DC-to-6 GHz bandwidth is required with moderate gain and low noise characteristics. The GaAs InGaP HBT process offers a balance of linearity and power efficiency. Consider the SOT-89-3 package constraints for thermal management and board space. Evaluate the 5 V supply requirement against system power budgets. Compare input return loss specifications against source impedance matching requirements.

Part Context

This part belongs to the HMC311 series of gain block amplifiers from Analog Devices. It is distinct from evaluation boards such as the HMC311ST89, which are separate hardware tools. The ETR suffix indicates a specific tape-and-reel packaging configuration for automated assembly. It serves as a discrete active component rather than a development kit or passive accessory.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Consult Analog Devices technical support for direct replacements or pin-compatible alternatives. Verify functional equivalence before substituting any components in existing designs.
