The Mini-Circuits ZFSC-2-2500 is a 2-way 0° coaxial power splitter/combiner operating across 10 MHz to 2500 MHz. This 50 Ω device splits or combines RF signals with minimal loss and high port isolation, making it essential for cellular, GPS, PCS/DCS, ISM, and satellite distribution systems. In-phase splitting ensures coherent signal distribution in multi-channel architectures.
