Low-power 2.63-GHz products are not a specific brand but a category of electronic components, often used in industrial and telecommunications applications. These products typically include RF amplifiers, transceivers, and other wireless communication devices designed for low-power consumption at 2.63 GHz frequencies. Companies like Texas Instruments (USA), Analog Devices (USA), and Infineon Technologies (Germany) manufacture such components, catering to industries such as IoT, industrial automation, and wireless infrastructure. These products are crucial for energy-efficient, high-performance wireless systems.
