1-Tone Nonlinear Simulations > Spectrum, Gain, Harmonic Distortion vs. Frequency & Power

Description

This simulation setup is identical to the HB1TonePswp schematic, except that frequency is swept in addition to available source power. It simulates the spectrum, output power, power gain, gain compression, phase distortion, harmonic distortion, and group delay of a device or amplifier, all versus available source power. A sample power amplifier is provided. You must replace this amplifier with your own device or amplifier, and modify the biases, as needed.

Needed to Use Schematic

A device or an amplifier using nonlinear model(s)

Main Schematic Settings

input frequency sweep range and available source power sweep range. The available source power sweep is divided into two parts, one coarse, and the other fine, for better resolution when the amplifier is being driven into compression.

Data Display Outputs

HB1ToneFPswp.dds, "Spectrum, Gain, Harmonics" page:

• All versus available source power, at a frequency selected by moving a marker:
  • Output power
  • Transducer power gain (power delivered to the load minus power available from the source)
  • Harmonic distortion up to the 5th, in dBc
  • Phase shift and gain reduction (relative to simulation at lowest input power level), for use in the GComp7 section of S2D data file, for behavioral modeling
• Group delay at one input power level selected by moving a marker
• Output spectrum at one input power and frequency, both selected by moving markers

HB1ToneFPswp.dds, "AM-to-AM, AM-to-PM Plots" page:

• All versus available source power, at a frequency selected by moving a marker:
  • AM-to-AM, AM-to-PM, characteristics
  • Output power
