T3 Mixer Primer: A Mixer for the 21st Century

Intermodulation distortion (IMD) suppression is a critical issue in modern military and commercial RF/microwave systems. Pressed by the demands imposed by distortion‐sensitive digital modulation formats, modern systems routinely specify linearity requirements that are impossible to attain using conventional approaches. To meet these new challenges, Marki Microwave has introduced the Two‐Tone‐Terminator (T3) mixer family. The T3 mixer is the most sophisticated mixer circuit on the market today and offers unparalleled performance when compared to all other mixer technologies. This Primer describes the key operating principles of the T3 mixer and compares the performance against traditional double balanced mixers.
