The Mini-Circuits ZFSC-2-4 is a 2-way 0° power splitter/combiner operating across 0.2 MHz to 1000 MHz with 50 Ω impedance. It splits or combines RF signals with minimal loss and high port isolation, making it suitable for cellular, VHF/UHF, and instrumentation systems. The device delivers typical insertion loss of 0.5 dB, port-to-port isolation of 25 dB (minimum 20 dB), and excellent amplitude and phase balance across its operating range.
