BLP5LA55SXY

Overview

The BLP5LA55SXY is an LDMOS power transistor manufactured by Ampleon, designed for high-performance radio frequency applications. It operates within the UHF frequency range of 470 MHz to 960 MHz and is housed in a TO-270-2F-1 package. The device delivers a typical output power of 55 W with a drain efficiency of approximately 60% at a standard operating voltage of 28 V. Key electrical characteristics include a gain of roughly 16 dB and a maximum drain current of 6 A. These specifications make it suitable for demanding RF power amplifier designs requiring robust performance and thermal stability.

Feature Summary

• High-efficiency LDMOS technology optimized for superior drain performance
• Integrated electrostatic discharge protection on both gate terminals
• Robust construction capable of withstanding high VSWR conditions
• Designed for ease of integration into RF power amplifier circuits

Applications

• UHF radio transmitters
• Industrial heating systems
• Medical equipment RF generators
• Broadcast transmitter amplifiers

Procurement Notes

Verify the specific suffix 'XY' against official Ampleon documentation to confirm exact binning or testing parameters. Ensure compatibility with existing thermal management solutions given the TO-270-2F-1 package constraints. Confirm that the intended application falls within the specified 470-960 MHz operational range for optimal performance.

Selection Notes

Select this component when designing UHF amplifiers requiring 55 W output power. Consider the 28 V supply requirement and the need for adequate heat sinking due to the power dissipation levels. Evaluate the 60% efficiency target against system thermal budgets. Compare gain requirements with the typical 16 dB specification to ensure sufficient drive capability.

Part Context

This part belongs to the BLP5LA series of LDMOS transistors from Ampleon. The series is characterized by its use in high-power RF applications across the UHF band. The TO-270-2F-1 package provides a balance between power handling capacity and mounting flexibility for industrial and broadcast environments.

Replacement Considerations

Check for direct cross-references in Ampleon's portfolio such as the BLP5LA55SG. Verify pinout compatibility and thermal resistance values before substituting with other manufacturers' devices to ensure circuit stability.
