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 webinar will provide an overview of areas 5G will address. We will begin with a discussion on the shortcomings of present day cellular systems to highlight the items needing to be addressed in 5G. Provide the overall 5G goals and pillar use cases as defined by ITU. Several deployment options will be provided and summary of the 3GPP scenarios provided. Key system parameters will be discussed and the impact of 5G to a Cloud-RAN network architecture will be highlighted.
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.
Instructor Scott Bullock presents a tutorial webcast on Satellite Communications. This one-hour webinar provides an overview and introduction to the unique issues related to space-terrestrial comms links.
