RF/Microwave Calculator and Converter Apps

I recently came across this very nice microwave toolbox for Android mobile devices that Faust Nijhuis developed (posted on our LinkedIn Community). He has created a free lite version with a few useful calculators and a 1.99 euro version that has 6 calculators and 2 converters for the full toolbox. Below are a couple of sample screen shots from his web site.


MW calculator lite is the lite and free version of the microwave tool box with the following tools:

• PI and T attenuator calculator
• Reflectometer calculator
• Mismatch error limits calculator

MW calculator is a microwave tool box with the following tools:

• PI and T attenuator calculator
• Reflectometer calculator
• Mismatch error limits calculator
• Microstrip calculator
• Stripline calculator
• Coplanar waveguide calculator
• Power and voltage converter
• Field intensity and power density converter

You will find the applications in the Android Market and more information can be found on his web site at http://www.mwave-design.nl/mw/index.php?title=Android.

At IMS 2010, Agilent launched the Agilent MicroWave calculator to help calculate the errors in microwave measurements. It consists of Directivity Error Calculator, Mismatch Error Limit Calculator, and Ratio-to-dB Calculator. The Directivity Error Calculator shows the accuracy of a reflection measurement of unknown impedance based upon the directivity of the coupler used for the measurement. The Mismatch Error Limit Calculator shows the potential error in a transmission measurement due to imperfect source match and load match. The Ratio-to-dB Calculator simply converts between voltage ratio, power ratio, and dB.

Please let us know if there are RF/microwave related tools that you would like to have in an app. What other mobile phone apps have you seen that would be useful to microwave engineers? This should be a very interesting area to watch as new apps are developed for our industry.
