This online program has been designed for applications, production, manufacturing engineers and technicians as well as other professionals who need to have a solid background in the fundamentals of working with RF and wireless products. This four part program provides a thorough understanding of RF analytical tools, communications signals, RF devices and test instruments. Starting with basic analytical tools such as the decibel scale, S-parameters and the Smith Chart, this program covers test instrumentation, RF components, and modulation.
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.
These lecture notes provide comprehensive coverage of mixer types as used in RF and microwave applications. Three approaches to producing the multiplication of two signals are described: using nonlinear behavior of a diode or transistor, switching, and sampling. Major mixer topologies are also introduced. These notes may be more detailed than what many people are looking for, but they are still worth reading over to gain an understanding of the different mixer strategies.
This app note gives a good understanding of the operation of switching type mixers. "Switching type" refers to the implementation of the mixing operation by using the diode or transistor as a switch that turns the RF signal on and off or inverts its polarity at the LO frequency. Another type of mixer implementation is to bias the diode so that it operates in the square law region so that the output includes the square of the input.
This blog explores various topics in RF test and measurement, from the latest equipment to best practice techniques to ensure consistent results and understand uncertainty limitations.
My name is Ben Zarlingo and I'm an applications specialist for Keysight Technologies. I've been an electrical engineer working in test & measurement for several decades now, mostly in signal analysis. For the past 20 years I've been involved primarily in wireless and other RF testing.
This connector identifier guide features schematic drawings of over 50 different connector types in each gender. The guide also features a chart comparing the maximum frequency capability of each type. A small glossary of RF terms is also included.
These presentation notes describe some best practices and potential pitfalls of using "lab" versus "general" precision connectors in your testing environment. In this paper, "lab" precision generally refers to the air-dielectric 3.5-mm and 2.92-mm connectors, while "general" precision refers to SMA-style connectors.
