BLF2425M7LS250P,11

Overview

The Ampleon BLF2425M7LS250P is a power LDMOS transistor designed for Industrial, Scientific and Medical (ISM) applications at frequencies from 2400 MHz to 2500 MHz. It is assembled in an earless flanged balanced ceramic package (SOT539B). The device supports high-power continuous wave (CW) operation with a drain-source voltage of 65 V and delivers 250 W output power at 28 V. Typical performance includes a gain of 15 dB and a drain efficiency of 51% at 2450 MHz. The junction temperature rating reaches 225 °C, and the thermal resistance from junction to case is 0.19 K/W.

Feature Summary

• High efficiency and excellent thermal stability
• Excellent ruggedness capable of withstanding VSWR = 10:1 through all phases
• Integrated ESD protection
• Internally matched for broadband operation

Applications

• RF power amplifiers for CW applications in the 2400 MHz to 2500 MHz frequency range
• Industrial heating systems
• ISM band applications

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm the package variant. The 'LS' designation indicates the earless flanged balanced ceramic package (SOT539B), whereas the 'L' version denotes the flanged package with mounting holes (SOT539A). Ensure compatibility with the intended PCB layout and mechanical mounting constraints before procurement.

Selection Notes

Select this component for high-power CW applications requiring robust performance in the 2.4 GHz ISM band. The device offers high efficiency and excellent ruggedness under mismatched load conditions. Consider the SOT539B earless package for designs requiring specific mechanical clearance or mounting configurations distinct from the standard flanged version.

Part Context

The BLF2425M7LS250P belongs to Ampleon's 7th generation LDMOS product line. It shares core electrical specifications with the BLF2425M7L250P but differs in physical packaging. Both variants are optimized for industrial and scientific applications, providing reliable power amplification in the 2400 MHz to 2500 MHz range.

Replacement Considerations

The BLF2425M7L250P serves as a direct functional substitute, differing only in package style (SOT539A vs. SOT539B). Verify mechanical fit and mounting hole alignment when swapping between these two variants.
