**Free Engineering Software for Downloading**

The following programs are free for ingdownload and use. They are utilities for electronics engineers. The programs were written by Dr. Ronen Holtzman as a useful tool for Elisra Microwave Division engineers. The software comes with no warranty.

__Power Converter__

This utility easily converts between the following properties: power in watts and dBm, peak and RMS voltage, and peak and RMS current. To download the software, click on the picture below:

__VSWR ____Converter__

This utility easily converts between the following properties: VSWR, Return Loss in dB and Reflection Coefficient. To download the software, click on the picture below:

__Air Inductor Calculator__

This utility helps with the design of air inductors. The utility gives an easy approximation for the number of turns needed to achieve a given inductance. The current eating is a limit set by the MIL-STD for long single wires. In practice this limit may easily be exceeded if a proper heat transfer is applied through the PCB using the pads of the inductor. To download the software, click on the picture below:
