Procurement Notes

Verify component authenticity through authorized channels as the part status is obsolete. Confirm that the specific suffix matches required specifications, noting that ordering suffixes do not inherently change function without explicit documentation. Request official datasheets and test reports to validate electrical parameters against original Analog Devices standards before integration.

Selection Notes

Select this component for applications requiring broadband amplification within the sub-3 GHz range. Consider the 175 mA current draw and 5V supply requirement for power budgeting. Evaluate the 6.5 dB noise figure and 27.5 dBm output power against system link budgets. Ensure thermal management supports the specified operating temperature range of -40°C to +85°C.

Part Context

This model belongs to the HMC454 series of high-power MMIC amplifiers. It utilizes GaAs InGaP HBT technology for robust performance. The ST89 designation indicates the specific SOT-89 surface mount package configuration. This family targets cellular and general RF applications requiring high linearity and moderate power output.

Replacement Considerations

Public records indicate the HMC454ST89ETR as a variant within the same product family. Verify pinout compatibility and electrical parameter equivalence before substitution. Cross-reference with Analog Devices documentation to confirm functional interchangeability.
