About Amplifier DesignGuide

The Amplifier DesignGuide has many simulation setups and data displays that are useful for amplifier design. The simulation setups are categorized by the type of simulation desired and the type of model available. Most of the simulation setups are for analysis, but there are also some for synthesizing impedance matching networks.

Note This manual assumes that you are familiar with all of the basic ADS program operations. For additional information, refer to the ADS Schematic Capture and Layout manual.

This manual is organized as follows:

• Reference tables in this chapter, listing all simulation setups, with links to the appropriate manual pages for detailed information
• Chapters for each type of simulation setup, as identified on the DesignGuide menu (which is accessed from ADS Schematic window). Detailed information on each simulation setup is included.

Note The Power Amplifier examples are not documented in detail, but for the list of data displays, refer to Power Amplifier Examples - By Class of Operation. For a list of references for these, refer to References for Power Amplifier Examples.
