Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific revision markings on the package. Ensure storage conditions adhere to moisture sensitivity level requirements. Validate that the received part matches the exact HMC311ST89TR designation before integration into designs.

Selection Notes

Select this component for applications requiring wideband amplification up to 6 GHz with moderate power output. Consider the 5 V supply requirement and 55 mA current draw for power budgeting. Evaluate thermal management needs given the 340 mW power dissipation. Compare against other HMC311 variants if different packaging or pinout configurations are required for the specific PCB layout.

Part Context

This part belongs to the HMC311 series of InGaP HBT gain block amplifiers. It shares functional similarities with other members like the HMC311LP3ETR but differs in physical packaging and electrical specifications. The ST89 variant specifically denotes the SOT-89-3 form factor, distinguishing it from QFN packages used in other series iterations.
