BLA6H0912LS-1000U

Overview

The BLA6H0912LS-1000U is a pulsed power LDMOS transistor designed for avionics transmitter applications in the 960 MHz to 1215 MHz frequency range. It delivers an output power of 1000 W with a typical drain efficiency of 51% and a power gain of 15.5 dB at 1030 MHz. The device operates with a drain-source voltage of 50 V and features a junction temperature rating up to 225 °C. Packaged in an earless flanged balanced ceramic SOT539B housing, it includes integrated ESD protection and internal matching for ease of use.

Feature Summary

• High ruggedness capable of withstanding a load mismatch corresponding to VSWR = 3:1 through all phases
• Internally matched for ease of use and high flexibility regarding pulse formats
• Integrated ESD protection compliant with electrostatic sensitive device handling standards

Applications

• Mode-S transponders
• TCAS (Traffic Collision Avoidance System)
• JTIDS (Joint Tactical Information Distribution System)
• DME (Distance Measuring Equipment)
• TACAN (Tactical Air Navigation)

Procurement Notes

Verify the specific ordering suffix against official Ampleon documentation to confirm package variations or testing conditions. Confirm RoHS compliance status and check for any export control regulations applicable to this component before finalizing procurement plans.

Selection Notes

Select this component for avionics systems requiring 1000 W pulsed power within the 960 MHz to 1215 MHz band. Ensure the design accommodates the SOT539B earless flanged package dimensions and utilizes Rogers Duroid 6002 PCB material for optimal impedance matching and thermal performance.

Part Context

This part belongs to the BLA6H0912L(S)-1000 family of LDMOS avionics power transistors. The LS variant specifically denotes the earless flanged balanced ceramic package (SOT539B), distinguishing it from the standard flanged version (SOT539A) while sharing identical electrical characteristics and application profiles.

Replacement Considerations

The BLA6H0912L-1000 serves as a direct functional equivalent within the same product family, differing only in the inclusion of mounting holes on the flange (SOT539A package). Verify mechanical fitment when substituting between the LS and L variants.
