1-Tone Nonlinear Simulations > Noise Figure, Spectrum, Gain, Harmonic Distortion

Description

This simulates the spectrum, output power, transducer power gain, and harmonic distortion of a device or amplifier at a single RF frequency and power, as well as its noise figure within a narrow band of frequencies around the RF frequency. A sample device is provided. You must replace this device 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 power, range of noise frequencies

Data Display Outputs

• Noise figure with Z0 ohm source impedance
• Minimum noise figure with the optimal source impedance
• Optimal source impedance and reflection coefficient versus noise frequency
• Output spectrum and voltage waveform
• Output power
• Transducer power gain (power delivered to the load minus power available from the source)
• Harmonic distortion up to the 5th, in dBc
