BLU6H0410LS-600P,1

Overview

The BLU6H0410LS-600P is a 600 W LDMOS RF power transistor designed for radar and industrial applications within the 400 MHz to 900 MHz frequency range. Measured at a duty cycle of 10% and pulse width of 1 ms, it operates with a drain-source voltage of 50 V and quiescent current of 1.3 A. At 860 MHz in a narrowband test circuit, it delivers 600 W peak output power with a typical gain of 20 dB and efficiency of 58%. The device features an internal input matching network and exhibits excellent ruggedness, supporting a VSWR of 40:1 through all phases.

Feature Summary

• Excellent ruggedness capable of withstanding high VSWR mismatches
• Internal input matching for high gain and broadband operation
• Optimized thermal behavior with low junction-to-case resistance

Applications

• Power amplifier for radar transmitter applications
• Industrial applications in the 400 MHz to 900 MHz range

Procurement Notes

Verify the specific package variant required for the design. The 'L' suffix indicates a flanged balanced ceramic package with mounting holes (SOT539A), while the 'LS' suffix denotes an earless version (SOT539B). Confirm RoHS compliance status and ensure ESD handling precautions are strictly followed during assembly and testing procedures.

Selection Notes

Select this component for high-power radar systems requiring robust performance under mismatched load conditions. Ensure the application supports pulsed Class-AB operation at the specified duty cycle. Verify that the PCB layout accommodates the specific SOT539A or SOT539B footprint dimensions and mounting hole configurations provided in the datasheet.

Part Context

This part belongs to Ampleon's BLU series of LDMOS transistors, which are engineered for high reliability in demanding RF environments. The BLU6H0410LS-600P shares core electrical characteristics with the BLU6H0410L-600P, differing primarily in the mechanical package configuration to suit different mounting requirements.

Replacement Considerations

The BLU6H0410L-600P serves as a direct functional equivalent with identical electrical specifications but utilizes the SOT539A package with mounting holes instead of the earless SOT539B form factor.
