Intermod distortion (IMD) suppression is a critical issue in modern systems. Pressed by demands of digital modulation formats, systems specify linearity that cannot be achieved with conventional approaches. This primer describes the T3 Mixer, the most sophisticated mixer circuit on the market today. This Marki Mixer offers unparalleled performance compared to other mixer technologies.
