Power LDMOS transistor

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

Features and benefits

  • Excellent ruggedness
  • High efficiency
  • Low thermal resistance providing excellent thermal stability
  • Decoupling leads to enable enhanced video bandwidth performance (75 MHz typical)
  • Designed for broadband operation (1805 MHz to 1995 MHz)
  • 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
  • For RoHS compliance see the product details on the Ampleon website


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