#262: IQ Modulator Basics: Operation, measurements, impairments

Video Description

This video discusses the basics of an IQ modulator, discusses and demonstrates its operation, shows a few typical modulation types as well as the effects of various impairments. It also shows the basic SSB Suppression test. I use a combination of a few Mini-Circuits mixers (ADE-1ASK) for much of the video, and also show one of their IQ Modulator modules (ZFMIQ-10M). As mentioned in the video, there are a few pre-requisite videos that are recommended to watch prior to this video: Basics of IQ Signals: https://www.youtube.com/watch?v=h_7d-m1ehoY Diode Ring Mixers: https://www.youtube.com/watch?v=junuEwmQVQ8 And a few for extra credit: IQ Signals Part II: https://www.youtube.com/watch?v=5GGD99Qi1PA Basics of RF Mixers: https://www.youtube.com/watch?v=Mm7WfVzr1ao Mixer LO drive level: https://www.youtube.com/watch?v=GvadQpkZ8l0 Notes from this video can be found here: http://www.qsl.net/w2aew/youtube/IQ_modulator_basics.pdf
