New features and changes introduced in this version are:

• New Plot Options Added to the Output Port Block

• Enhanced Noise Factor and Noise Temperature Visualization

• Physical Amplifier and Mixer Blocks Now Support Frequency-Dependent, Nonlinear Data

• Enhanced Downconverter Mixers

• Removed GammaMS and GammaML Polar Plot Options

New Plot Options Added to the Output Port Block

You can plot the following new parameters from the Visualization tab of the Output Port block:

• OIP3 for the XY Plot

• OIP3, NFactor, and NTemp for the Budget Plot

For the definition of each parameter, see Types of Plots.

Enhanced Noise Factor and Noise Temperature Visualization

You can now plot Noise Factor and Noise Temperature on an XY plot from the Visualization tab of all blocks in the Physical library.

Physical Amplifier and Mixer Blocks Now Support Frequency-Dependent, Nonlinear Data

You can now specify frequency-dependent nonlinear data on the Nonlinearity Data tab of all physical amplifier and mixer blocks. For more information about how to do this specification, see Modeling Nonlinearity.

Enhanced Downconverter Mixers

Mixer blocks now model spectral inversion for down-converter physical mixers. As a result, blocks from the Mixers library no longer error out when you set the Mixer type parameter to Downconverter and the local oscillator frequency (LO) is greater than the input RF frequency.

Removed GammaMS and GammaML Polar Plot Options

You can no longer display GammaMS and GammaML on a Polar Plot from the Visualization tab of the Output Port block. These parameters are useful for detailed RF analysis, but not for the system-level RF analysis that RF Blockset software supports. In some cases, using RF Blockset software to plot these parameters can lead to incorrect results.

Compatibility Considerations

Your existing models that plot GammaMS and GammaML will not longer plot these parameters. Instead, the models will plot the default parameter for the Polar Plot when you run the model and click the Plot button in the Visualization tab of the Output Port block. Use RF Toolbox™ software to perform detailed RF analysis.
