RF Adapters are passive components used in signal transmission systems for Radio Frequency applications (typically 3 kHz to 300 GHz frequency band). These adapters facilitate reliable connections and signal conversion between different RF interface types, impedances, or transmission media, ensuring low loss, minimal reflection, and high stability during RF signal transmission. Widely used in communication, radar, test and measurement, aerospace, and medical equipment applications.
