Procurement Notes

Verify the manufacturer source carefully, as this part number appears under both M/A-COM Technology Solutions and Tyco Electronics in public records. Confirm the specific datasheet version matches the required electrical characteristics. Ensure the component meets current RoHS compliance requirements before procurement. Cross-reference the ordering suffix if available to confirm package type and material specifications.

Selection Notes

Select this component when a low-power (2W) solution is required for the 1615-1685 MHz band. Compare against higher power variants like the PH1617-30 or PH1617-60 if greater output is needed. Consider the internal matching capabilities to reduce external passive component count. Verify thermal management requirements align with the package's dissipation capabilities.

Part Context

This transistor belongs to a family of wireless bipolar power transistors from M/A-COM. Related parts include the PH1617-30 and PH1617-60, which offer higher power outputs in the same frequency range. Lower power alternatives such as the PH1516-2 exist for different bandwidths. The series shares common design features like internal matching and gold metallization.

Replacement Considerations

Publicly confirmed direct substitute part numbers are not explicitly listed in the provided documentation. Engineers should evaluate the PH1617-30 or PH1617-60 for higher power needs, though pinouts and thermal characteristics must be verified. No other specific replacement models are documented in the source data.
