# S-Parameter Viewer & RF Synthesis Tools

## Introduction

This is a comprehensive toolkit for RF and microwave circuit design. It combines S-parameter visualization capabilities with synthesis tools for filters, matching networks, attenuators, and power combiners. Additionally, a number of simple RF engineering calculators are available in the menu bar at the top of the window.

## Features

### Data Display

The tool can display S-parameter data in various formats, including polar plots and Smith charts. Data markers are supported in each display widget. Additionally, the magnitude display supports limit lines.

### Data Management

This tool can read data from Touchstone files and Qucs-S datasets. Users can easily manage files and traces using the data tabs to add and remove data. Sessions can be saved into a file for later use.

### Design Tools

The tool includes built-in design tools such as:

- RF Circuit Synthesis Tools

- RF Engineering Calculators
