BLF10H6600PSU

Overview

The BLF10H6600PSU is a 600 W LDMOS RF power transistor designed for transmitter and industrial applications. It operates in the 400 MHz to 1000 MHz broadband range with an internal input matching network. The device features excellent ruggedness, supporting VSWR ≥ 40:1 through all phases. In a common source narrowband test circuit at 860 MHz, it delivers 250 W average output power with 20.8 dB gain and 46% drain efficiency under class-AB conditions. Pulsed operation at 860 MHz yields 600 W peak output power with 19.8 dB gain and 58% efficiency. The component utilizes a flanged balanced ceramic package (SOT539B) with four leads.

Feature Summary

• Excellent ruggedness capable of withstanding high voltage standing-wave ratios
• Internal input matching network for optimized broadband performance
• High thermal reliability with low junction-to-case thermal resistance

Applications

• Communication transmitter applications
• Industrial applications

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm the exact package variant. Ensure that the procurement channel provides original manufacturer data sheets to validate the component specifications and authenticity before integration into designs.

Selection Notes

Select this component for designs requiring high power output within the 400 MHz to 1000 MHz frequency range. Consider the SOT539B earless flanged package for mounting constraints. Evaluate thermal management requirements based on the specified junction-to-case thermal resistance to ensure reliable operation under continuous or pulsed load conditions.
