Description

A 4-way power splitter operating in the 150–1000 MHz range is a passive RF device designed to evenly distribute an input signal into four output paths, each carrying approximately one-quarter of the original signal power. It plays a crucial role in systems where a single RF source needs to feed multiple components—such as antennas, receivers, or analyzers—without introducing significant signal degradation. Internally, it uses a network of transmission lines or Wilkinson-style dividers to ensure minimal insertion loss (typically around 6.6 dB), excellent port-to-port isolation (around 18 dB), and a low VSWR (≤1.3), which ensures efficient impedance matching. With a power handling capacity of up to 50 watts and low passive intermodulation (≤ -150 dBc), this splitter is well-suited for demanding applications like public safety communications, RF testing environments, and drone detection systems. Its rugged design, often with N-type connectors and weather-resistant housing, makes it suitable for both indoor and outdoor deployments.
