BLL6H1214LS-500,11

Overview

The BLL6H1214LS-500,11 is an LDMOS power transistor designed for L-band radar applications operating between 1.2 GHz and 1.4 GHz. It delivers a typical output power of 500 W with a drain efficiency of 50% and a power gain of 17 dB under pulsed RF conditions (300 µs pulse width, 10% duty cycle). The device operates at a drain-source voltage of 50 V and features a maximum drain-source breakdown voltage of 100 V. Packaged in the SOT539B earless flanged balanced ceramic format, it includes integrated ESD protection and internal matching to simplify circuit design.

Feature Summary

• High flexibility regarding pulse formats
• Excellent ruggedness and thermal stability
• Internally matched for ease of use

Applications

• L-band power amplifiers for radar applications in the 1.2 GHz to 1.4 GHz frequency range

Procurement Notes

Verify the specific ordering suffix against official Ampleon documentation to confirm package variant and compliance status. Ensure that the procurement channel provides valid traceability for this sensitive semiconductor component. Confirm RoHS Directive 2002/95/EC compliance requirements are met through authorized distribution channels prior to finalizing acquisition.

Selection Notes

Select this component for high-power L-band radar systems requiring robust performance within the 1.2 GHz to 1.4 GHz spectrum. Evaluate thermal management capabilities based on the specified transient thermal impedance values. Ensure the application environment supports the required class-AB operation parameters and respects the absolute maximum ratings for junction temperature and voltage limits.

Part Context

This part belongs to the BLL6H1214 series of LDMOS transistors from Ampleon. It shares core electrical specifications with the BLL6H1214-500 but utilizes the SOT539B package, which is an earless flanged balanced ceramic package. This variation offers four leads without mounting holes, providing a distinct mechanical form factor while maintaining identical RF performance characteristics.

Replacement Considerations

The BLL6H1214-500 serves as a direct functional equivalent within the same product family. Designers must account for the mechanical differences between the SOT539A and SOT539B packages when substituting components.
