Procurement Notes

Verify component authenticity through authorized M/A-COM distributors or direct manufacturer channels. Confirm that the received unit matches the marking PR2731-115M. Ensure storage conditions remain within the specified -65°C to +200°C range to maintain junction integrity. Request current engineering samples or test data as volume production commitment may not be guaranteed for this preliminary specification.

Selection Notes

Select this component when designing circuits requiring 115W pulsed output at 2.7-2.9 GHz. Ensure the thermal management solution can handle the specific dissipation requirements under 200µs pulse conditions. Verify that the load mismatch tolerance of 2:1 and stability VSWR of 1.5:1 align with the system's antenna characteristics. Consider the fixed mechanical outline for PCB footprint compatibility.
