Visualize your RF system a better way
Now you can build your RF systems in a modern environment for easy cascaded analysis. Drop generic or custom symbols on a canvas and connect them as you would in a schematic capture tool. Your design is stored in our cloud and can be easily shared with other users or exported to PDF for inclusion in presentations and white papers.
S Parameters files
S-parameters can be imported by opening a symbol card and dropping the file into the box provided. Multiple s-parameter files can be imported for different temperature profiles as shown here. The simulator will interpolate between frequencies and temperatures in multiple files simultaneously.
If you do not have an s-parameter file, each symbol card has the ability to accept frequency/gain data by manual input. As shown in the screenshot here, simply click on the “MULTIPLE VALUES” tab and open the drop down input window to begin inputing the data.
All active stages account for compression. Gain, noise power, and noise are computed in compression states. The compression knee (P1dB) and saturation point (Psat) are easily modified via the parameter interface.
A backoff power level can be set; when this level is exceeded, the stage will turn yellow. When the level exceeds P1dB, the stage will turn red.
SpLitter and Combiner
These type of elements are used extensively in RF design. RFgraph delivers a robust model that both allows for parameter flexibility while maintain independent splitter legs for simulation.
The splitter/combiner analyzes independent legs over a wide variety of complicated splitter/combiner paths and computes path-specific cascaded outputs like gain, noise power, noise figure, compression results, and much more.
RFgraph has a growing library of generic symbol cards that are ready to use. These symbol cards have base case parameters already set.
Simply modify a symbol element, such as an amplifier, to your specifications and save it to your custom library for future use.
RFgraph also has several example designs that can be copied and customized to get you designing right away!
