Yes Details below	Yes—Details labeled as Compatibility Considerations, below. See also Summary.	Bug Reports at Web site

New features and changes introduced in this version are:

• Enhanced Frequency-Dependent Noise Modeling for Amplifier and Mixer Blocks

• New Demo for Radar Systems

Enhanced Frequency-Dependent Noise Modeling for Amplifier and Mixer Blocks

The RF Blockset™ amplifier and mixer blocks from the Physical library now support more advanced calculations of nonlinear effects. In particular, this enhances the behavior of the following blocks:

• General Amplifier and General Mixer

• S-Parameters Amplifier and S-Parameters Mixer

• Y-Parameters Amplifier and Y-Parameters Mixer

• Z-Parameters Amplifier and Z-Parameters Mixer

Compatibility Considerations

For each of the physical Amplifier and Mixer blocks, a new field, Gain compression at saturation, appears under the Nonlinearity Data tab in the block dialog boxes. The various parameters specified under this tab control the method by which these blocks handle nonlinear effects. See the related documentation for more information.

New Demo for Radar Systems

The new Radar Tracking System demo is relevant to aerospace defense applications. The demo contains two RF subsystems: an RF transmitter and an RF receiver, both of which use RF Blockset components. This demo requires Communications System Toolbox™.
