Besser Associates and Microwave Journal magazine have presented a free webcast on Mixers and Frequency Conversion. This one-hour webcast has been presented by instructor Allen Podell, and the recording is now available for viewing. Frequency conversion is a critical function in all wireless systems. A key component used to accomplish this is the mixer. Designers need to understand different mixer topologies and specifications in order to meet their system requirements.
These courses focus on CDMA/OFDM fundamentals as well as the techniques that have been incorporated into 5G/4G LTE/Advanced specifications. Topics covered include 5G Wireless Networks, mm-Wave Antennas, Smartphone Architecture, and more.
In this practical tip from InCompliance magazine, instructor Arturo Mediano discusses the importance of using the actual load of your device rather than substituting and equivalent resistor when testing for EMI.
Mismatch uncertainty is the result of reflections adding and subtracting from each other when more than one interface is present.
