SR/087: How Dual Channel Pulse Testing Simplifies Characterizing RF Transistors
RF and higher power transistors suffer from self-heating and/or trapping effects. These effects, also called dispersion, result in a non-linear response at higher signals. To model the non-linear behavior properly, large signal characterization must be performed. Using pulse IV techniques to characterize the large signal behavior is popular because the interpretation of results leverages existing DC analysis and understanding.

Target Audience:
  • Those interested in pulse I-V testing of RF or higher power transistors
  • Device engineers using III-V (compound semiconductor) or silicon (LDMOS) to design or test RF or higher power transistors.

What you will learn:
  • Review of large signal analysis characterization methods
  • Explanation of pulse IV test challenges
  • Review of oscillation issues when performing pulse IV testing of RF Transistors
