Low-power 2.53-GHz products are not a specific brand but rather a category of electronic components or devices operating at the 2.53 GHz frequency with energy-efficient designs. These products are typically used in industries such as telecommunications, IoT (Internet of Things), and industrial automation, where low power consumption and reliable wireless communication are critical. They may include RF modules, transceivers, or embedded systems from manufacturers like Texas Instruments (USA), STMicroelectronics (Switzerland), or Nordic Semiconductor (Norway). These components are often sourced from global electronics suppliers like Radwell or Grainger, catering to industrial and commercial applications.
