Mixers and modulators are not a specific brand but a category of industrial and electronic components used in signal processing and communication systems. These devices are produced by various manufacturers worldwide, including companies like Mini-Circuits (USA), Analog Devices (USA), and Murata Manufacturing (Japan). Mixers are used to combine or modulate signals in RF (radio frequency) and microwave applications, while modulators alter carrier signals for data transmission. They serve industries such as telecommunications, aerospace, defense, and broadcasting. Companies like Radwell International and Grainger distribute these components alongside other industrial automation and electrical products.
