RF FDAs (Radio Frequency Frequency Division Amplifiers) are a category of industrial electronic components rather than a specific brand. These devices are commonly used in the telecommunications, broadcasting, and signal processing industries to amplify radio frequency signals. They are produced by various manufacturers worldwide, including companies like Analog Devices (USA), Qorvo (USA), and Infineon Technologies (Germany). RF FDAs are essential for applications such as wireless communication, radar systems, and test equipment. Key products include broadband amplifiers, low-noise amplifiers (LNAs), and power amplifiers (PAs), designed to meet stringent performance and reliability standards in industrial and commercial settings.
