BLF184XRGJ

Overview

The BLF184XRGJ is a 700 W LDMOS power transistor designed for broadcast and industrial applications in the HF to 600 MHz band. It features an earless flanged SOT1214C ceramic package with four leads. The device operates at a drain-source voltage of 50 V with a breakdown voltage of 135 V. At 108 MHz, it delivers 700 W pulsed output power with 23.9 dB gain and 73.5% drain efficiency. Continuous wave operation at the same frequency yields 750 W output with 23.5 dB gain and 81.9% efficiency. The junction-to-case thermal resistance is 0.18 K/W.

Feature Summary

• Integrated electrostatic discharge protection
• Excellent ruggedness capable of withstanding high voltage standing-wave ratios
• High efficiency and excellent thermal stability
• Broadband design suitable for HF to 600 MHz operations

Applications

• Industrial, scientific and medical applications
• Broadcast transmitter applications

Procurement Notes

Verify the specific ordering suffix against official Ampleon documentation to confirm packaging variations or compliance updates. Ensure compatibility with standard flange mounting requirements for the SOT1214C package. Confirm RoHS directive compliance status prior to integration into final assemblies.

Selection Notes

Evaluate thermal management capabilities based on the specified junction-to-case thermal resistance. Verify that the application circuit can support the required quiescent current and gate-source voltage limits. Consider the device's ruggedness specifications when designing for potential load mismatch conditions.
