RFGraph Features
Visualize your RF system a better way
Graphical Platform
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
This is a PRO feature
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.
Visualize Compression
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.
Multiple Values
This is a PRO feature
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.
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.
Custom Components
This is a PRO feature
If you have a very specific component that you need to use then it can be useful to save it as a custom component in your account. Custom components are copies of the default components, but with the parameters tailored to your exact requirements. You can drag and drop your custom components, just like with the default ones, and you can reuse them across all of your graphs.
Component Library
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!
Mirrored Components
This is a PRO feature
Mirrored components are components that always have the same parameter values. For example, if you change the NF value on one component, all the mirrors of that component will be updated to have the same NF value.
