ETL Systems presents a series of passive L-band transformers between 50Ω to 75Ω impedance that are available in DC & 10 MHz pass on both ports, DC & 10 MHz block on both ports, and DC block and 10 MHz pass on both ports. Standard packaging is available with all models, and a tubular package style is available for models with DC & 10 MHz pass on all ports. Components are available with 50Ω SMA, N-type, BNC and 75Ω BNC or F-type RF connector types. Applications for these transformers include telecom infrastructures, satellite systems, microwave links, test and instrumentation, military communications, and radar networks.
