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

Description

This simulation setup is identical to the HB1Tone schematic, except that available source power is swept. It simulates the spectrum, output power, power gain, gain compression, phase distortion, and harmonic distortion 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 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

HB1TonePswp.dds, "Spectrum, Gain Comp., Harmonics" page:
All versus available source power:

• Output spectrum and voltage waveforms
• Output power
• Transducer power gain (power delivered to the load minus power available from the source)
• Harmonic distortion up to the 5th, in dBc
• Output voltage waveforms
• 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

HB1TonePswp.dds, "AM-to-AM, AM-to-PM Plots" page:
All versus available source power:

• AM-to-AM, AM-to-PM, characteristics
• Output power
