Mismatch uncertainty is the result of reflections adding and subtracting from each other when more than one interface is present.
To use the calculator below, input a values into the fields and hit the enter key. The result will appear below.
You can choose different input formats from the drop down menu.
This workbook from the RF Technology Certification program demonstrates how to convert from dBm to milliwatts using approximation techniques without a calculator. An interactive calculator at the end demonstrates the process with values that you can enter yourself to practice.
This interactive web page allows you to look at the output waveforms from a switching-type mixer, as well as a pure multiplication. You can change the RF and LO frequencies and update the graph.
This demo is included in the Online RF Technology Certification program from Besser Associates.
eCalc was formerly its own product/website but more recently has been incorporated into the EEWeb collection of engineering tools. It is a streamlined multi-function calculator, with unit conversion and several built-in scientific constants, that can be customized to suit the users preferences (including RPN operation!). The free online version runs without any special plug-ins required. Downloadable versions can be purchased for Windows and Mac OS (free trial available).
The electronics and electrical engineering tools section of the EEWeb site features several online calculators for RF and PCB related problems. The page also features links to graph paper templates (standard, log/log, etc.) that you can download and print as well as reference sheets on trigonometric identities, algebra, and integrals.
Software for Windows PC's with multiple calculators for PC board parameters.
The Saturn PCB Toolkit is the best resource for PCB related calculations you can find.
It incorporates many features that PCB designers and engineers are in regular need of like current capacity of a PCB trace, via current, differential pairs and much more. Please download our PCB Toolkit today for free and enjoy!
