The ZN4PD1-183W+ from Mini-Circuits is a 4-way power splitter/combiner that operates from 4000 to 18000 MHz. It is capable of handling up to 30 W RF input power as a splitter and passing up to 4 A DC current from the sum port to all output ports (100 mA each port). This device provides high port-to-port isolation, excellent VSWR and low amplitude and phase unbalance. It is available in a rugged aluminum alloy module with SMA connectors and is ideal for electronic warfare, satellite instrumentation, wideband test and measurement applications.
