HMC454ST89ETR

Overview

The HMC454ST89ETR is a high dynamic range GaAs InGaP HBT MMIC amplifier manufactured by Analog Devices Inc. It operates within a frequency range of 400MHz to 2.5GHz and utilizes a SOT-89 surface-mount package. The device requires a 5V supply voltage with a typical current consumption of 175mA. Key electrical specifications include a gain of 12.5dB, a noise figure of 6.5dB, and a P1dB output power of 27.5dBm at a test frequency of 2.15GHz. This component is classified as a general-purpose RF amplifier.

Feature Summary

• High dynamic range performance utilizing GaAs InGaP Heterojunction Bipolar Transistor technology
• Integrated monolithic microwave integrated circuit (MMIC) design for compact implementation
• Surface-mount construction in a SOT-89 package for automated assembly

Applications

• GPS receiver front-end stages
• General purpose RF signal amplification
• Wireless communication infrastructure components

Procurement Notes

Verify the specific suffix ETR against official Analog Devices documentation to confirm tape-and-reel packaging configuration. Confirm RoHS3 compliance status through current datasheets. Check for Product Change Notices or End-of-Life announcements prior to procurement, as availability may be restricted. Ensure compatibility with existing PCB footprints designated for TO-243AA/SOT-89 packages.

Selection Notes

Select this component when a wide bandwidth from 400MHz to 2.5GHz is required with moderate gain. Consider the 175mA supply current for power budget calculations. Evaluate the 6.5dB noise figure against system sensitivity requirements. Compare the 27.5dBm P1dB capability with linearity needs relative to alternative MMICs in the same package family.

Part Context

This part belongs to the HMC454 series of high dynamic range amplifiers. It shares the SOT-89 form factor with other ADI MMICs but offers distinct frequency and gain characteristics tailored for broadband applications. The device represents a solid-state solution replacing discrete transistor designs in RF front-ends.

Replacement Considerations

No public confirmed substitute part numbers are documented for this specific model.
