Procurement Notes
Verify component authenticity by checking the manufacturer marking against official MACOM documentation. Confirm RoHS compliance status through the specific datasheet revision. Ensure the ordering suffix matches the required package configuration. Request the latest test data sheet to validate performance specifications prior to integration into avionics designs.
Selection Notes
Select this component for applications requiring pulsed RF power within the 1030-1090 MHz band. Evaluate thermal management requirements based on the 1.5°C/W junction-to-case thermal resistance. Consider the 250µs pulse duration and 10% duty cycle constraints when designing the drive circuitry. Verify that the system can accommodate the specified collector-emitter breakdown voltage of 70V.
