by Doug Jorgesen A high frequency tone or carrier is defined by two parameters: the magnitude and phase. In many applications it is required to modify the magnitude and phase of a carrier to an [...]

1. Top 7 Ways to Create a Quadrature (90˚) Phase Shift We’ve talked a lot about IQ mixers in the last few posts, about their theoretical underpinnings and applications as a phase detector and [...]

For many years Marki Microwave has sold Image Reject and Single Sideband Mixers to both laboratory/research customers and industrial/military customers. Due to the advancement of digital to [...]

The IQ mixer is the backbone of modern communications architectures, as well as advanced vector signal analyzers for electronic warfare and test and measurement receivers. The backbone of the IQ [...]

Sometimes you need a mixer; sometimes you need an IQ mixer. How do you know which one to buy? Before answering this question, I recommend reading the Mixer Basics Primer to get a good [...]

We’ve talked a lot about IQ mixers in the last few posts, about their theoretical underpinnings and applications as a phase detector and phase modulator. In upcoming posts we will discuss [...]

In our last post we showed the physical basis for how mixers are used as phase detectors, concluding by showing that IQ mixers make ideal phase detectors due to their ability to unambiguously [...]
