WM4PD-2-18-S is a wideband 4-way in-line power splitter covering the continuous bandwidth of 2 to 18 GHz in an aluminum enclosure measuring 4.00 x 2.50 x 0.38 inches. This covers several of the octave letter bands used by the military including S, C, X and Ku bands. The device is RoHS compliant, however lead solder is available on special order for high reliability military applications. Excellent VSWR and insertion loss, and 0.3dB typical amplitude balance across the band. Connectors are stainless steel for durability. Our own unique design maximizes bandwidth in a small size. Assembled and tested in USA. In continual production since 2015.
