Breakthrough LDMOS Power From Richardson Electronics: Freescale's MRFE6VP61K25 Sets Ruggedness Standard At 1.25 kW

Freescale Semiconductor has introduced the first 50V LDMOS power transistor that can deliver its full rated output power of 1.25kW after withstanding a load mismatch VSWR of 65:1 – across ALL phase angles. This extreme ruggedness capability represents a major advancement over the current RF power transistor choices for designers of defense/aerospace amplifiers, CO₂ laser exciters, plasma generators, magnetic resonance imaging (MRI) RF amplifier systems, particle accelerator amplifiers, FM and DVB-T broadcast amplifiers, and a wide variety of HF/VHF communications equipment linear amplifiers over the frequency range from 1.8 to 600 MHz.

Additional important features of the MRFE6VP61K25H/HS include:

• Device can be used single-ended or in a Push-Pull configuration.
• Robust 24dB gain allows for fewer stages in many amplifier designs.
• Low Thermal Resistance.
• Characterized from 30V to 50V supply voltage.
• Capable of 1250 Watts CW or Pulse operation.
• Available in both bolt-down and solder-down ceramic packaging.

A quick demonstration video is available (Lab Demo - High Rugged Test) regarding the enhanced ruggedness at 65:1 load VSWR (all phase angles) for this family of LDMOS high-powered transistors from Freescale Semiconductor.
