Version 2.2 (R2008a) RF Blockset™ Software Release Notes

Version 2.2 (R2008a) RF Blockset™ Software

This table summarizes what's new in V2.2 (R2008a):

New features and changes introduced in this version are:

• Baseband-Equivalent Modeling Enhanced

• Demos Updated

Baseband-Equivalent Modeling Enhanced

Two new Input Port block parameters provide better control of baseband-equivalent modeling:

• Fractional bandwidth of guard bands lets you specify Tukey windowing to reduce ringing and other artifacts in the baseband-equivalent model.

• Modeling delay (samples) lets you specify a delay to ensure that the baseband-equivalent model has a causal response.

For more information about these parameters and how to use them, see the Input Port block reference page and Creating a Complex Baseband-Equivalent Model.

Note   If you create a model using RF Blockset™ Version 2.2 and run it in previous versions of the software, two things happen: The blockset issues warnings indicating that the Input Port block does not have these two parameters. The blockset ignores the values of these two parameters, and uses their default values. To avoid these warnings, use the Simulink® Save As option to save the model in an earlier format, as described in Saving a Model in Earlier Formats in the Simulink documentation.

Demos Updated

The Touchstone^® Data File for 2-Port Bandpass Filter demo now uses more realistic data.

The following demos now show how to display passband frequency values on the Spectrum Scope block:

• Data File for Amplifier

• Intermodulation Analysis of Physical Amplifier
