PA designers get new EDA features

21 May 2003 Design Automation

Agilent eeSOF EDA recently announced three new DesignGuide utilities and a new application guide in the latest version of the Agilent Advanced Design System (ADS 2003A) electronic design automation (EDA) software. The features are tightly integrated into ADS 2003A to help power amplifier design engineers accelerate time-to-market by automating many time-consuming steps in the design process.

According to Agilent, the Transistor Bias utility improves design flow by automating the biasing of Bipolar, MOSFET and GaAs devices. It automatically extracts transistor DC parameters and synthesises an appropriate network to achieve a given bias point. The resulting transistor performance is verified and displayed graphically.

The Smith Chart and Matching utilities can automatically synthesise matching networks, accelerating the design process. The Smith Chart's graphical user interface allows the designer to create a matching network topology and watch the frequency response in realtime. The Matching utility allows for both narrow-band and broadband matching. The Matching software transforms a matching networks' lumped components to ideal transmission lines and microstrip elements.

The Load Pull application guide allows designers to import load-pull data from Focus Microwave and Maury Microwave load-pull systems. The scattered data interpolation is used to generate load- and source-pull contours for measuring multiple parameters simultaneously. This data can then be used with impedance matching to synthesize matching networks.
