BLA8H0910LS-500U

Overview

The BLA8H0910LS-500 is a 500 W LDMOS power transistor designed for avionics applications in the 900 MHz to 930 MHz frequency range. It operates at VDS = 50 V and delivers 500 W output power with 61% drain efficiency in continuous wave mode at Tcase = 65 °C. The device features an internally matched input and integrated ESD protection, housed in an earless flanged ceramic SOT502B package.

Feature Summary

• High efficiency operation
• Easy power control
• Excellent ruggedness
• Integrated ESD protection
• Internally input matched

Applications

• Avionics applications in the 900 MHz to 930 MHz frequency range

Procurement Notes

Verify the specific ordering suffix 'U' against official Ampleon documentation to confirm packaging details. Ensure compliance with RoHS Directive 2002/95/EC requirements. Confirm availability through authorized distributors or direct manufacturer channels.

Selection Notes

Select this component for high-power CW avionics systems requiring broadband performance between 900 MHz and 930 MHz. Consider the SOT502B earless flanged ceramic package for thermal management and mounting constraints. Verify class-AB biasing conditions for optimal gain and efficiency.

Part Context

This part belongs to the BLA8H0910L(S)-500 series of power LDMOS transistors from Ampleon. It shares specifications with the BLA8H0910L-500 variant, differing primarily in the physical package configuration (SOT502B vs SOT502A). Both are engineered for robust RF power amplification in demanding environments.

Replacement Considerations

The BLA8H0910L-500 serves as a functional equivalent within the same series, distinguished by its SOT502A flanged ceramic package with mounting holes instead of the SOT502B earless version.
