BLA1011-10

Overview

The BLA1011-10 is an avionics LDMOS transistor manufactured by NXP Semiconductors, formerly Philips Semiconductors. It is a single-channel enhancement-mode N-channel device designed for high-power RF applications. The component features a maximum drain current of 2.2 A and a maximum power dissipation of 25 W. It operates at temperatures up to 200 °C. The transistor utilizes metal-oxide semiconductor technology and is packaged in a configuration suitable for surface or panel mounting.

Feature Summary

• High power gain capability
• Easy power control characteristics
• Excellent ruggedness for reliable operation
• Source on mounting base eliminates DC isolators

Applications

• Avionics transmitter applications
• Frequency range operations between 1030 MHz and 1090 MHz

Procurement Notes

Verify the manufacturer designation carefully as this part originates from Philips/NXP rather than Ampleon. Confirm RoHS compliance status as documentation indicates unknown reach applicability code. Ensure the specific package variant matches the design requirements since packaging details are not explicitly defined in the summary data. Cross-reference with current NXP product specifications to confirm availability and supersession status relative to older Philips data sheets.

Selection Notes

Select this component for avionics systems requiring robust LDMOS performance in the 1030 to 1090 MHz band. The source-on-base design simplifies circuit topology by removing the need for common mode inductance management via DC isolators. Verify thermal management capabilities given the 200 °C maximum operating temperature rating. Ensure the 25 W power dissipation limit aligns with the system's peak load requirements.

Part Context

This transistor belongs to the discrete semiconductor category within the NXP/Philips portfolio. It serves as a specialized solution for aviation communication transmitters. The datasheet M3D381 supersedes earlier October 2002 documentation, indicating ongoing support for legacy avionics designs. It represents a transition period component between Philips and NXP branding eras.

Replacement Considerations

Consult NXP official substitution guides for updated avionics LDMOS alternatives. Verify pinout compatibility if replacing in existing PCB layouts. Check for newer generations that may offer improved ruggedness or gain characteristics while maintaining the same form factor.
