This test bench project shows a one tone swept power single frequency test bench for power amplifiers.

This test bench includes:

Schematics:

  • PA_One_Tone_Sweep_Power - the test bench setup.  Includes notes on where to change settings specific to your design
  • PA_One_Tone_Sweep_Power_Display - embeds all graphs into one display

Graphs

    • DC Current: DC Current from the DC Voltage source on the output of the transistor in the DUT subcircuit, plotted at a fixed frequency versus input power.
    • DC Drain Efficiency: DCRF measurement plotted at a fixed frequency versus input power.
    • Gain Power gain plotted at a fixed frequency versus input power.
    • Harmonic Powers: Power in the fundamental, 2nd and 3rd order harmonics at a fixed frequency versus input power.
    • Input and Output Current Waveforms: Current waveforms at the input and output of the DUT at a fixed frequency and power where the tuner controls the power level.
    • Input and Output Voltage Waveforms: Voltage waveforms at the input and output of the DUT at a fixed frequency and power where the tuner controls the power level.
    • PAE: Power Added Efficiency at a fixed frequency versus input power.
    • PAE vs Output Power: Power Added Efficiency at a fixed frequency versus output power.
    • Spectrum: Power Spectrum at the input and output of the DUT at a fixed frequency and power where the tuner controls the power level.
    • Total Harmonic Distortion: THD calculated in the output equations, at a fixed frequency versus input power.
    • Total Power Total power at the output and power and available power at the input at a fixed frequency versus input power.

Output Equations

  • PA_One_Tone_Sweep_Power - equations used to calculate the total harmonic distortion.
