Power LDMOS transistor

400 W LDMOS power transistor with improved video bandwidth for base station applications at frequencies from 1805 MHz to 1995 MHz.

Features and benefits

  • Decoupling leads to enable improved Video BandWidth (VBW) (120 MHz typical)
  • High efficiency
  • Low Rth providing excellent thermal stability
  • Designed for broadband operation
  • Lower output capacitance for improved performance in Doherty applications
  • Designed for low memory effects providing excellent pre-distortability
  • Internally matched for ease of use
  • Integrated ESD protection
  • Design optimized for gull-wing
  • Excellent ruggedness
  • Compliant to Directive 2002/95/EC, regarding Restriction of Hazardous Substances (RoHS)

Applications

  • RF power amplifiers for base stations and multi carrier applications in the 1805 MHz to 1995 MHz frequency range
