WM4PD-18-40-K

The WM4PD-18-40-K from Werbel Microwave is a 4-way power divider operating across 18 to 40 GHz, featuring 2.92 mm female connectors and a 50-ohm impedance. It provides a minimum return loss of 12.7 dB (1.6:1 VSWR) at all ports, with insertion loss above the theoretical 6 dB split ranging from 1.5 to 2.2 dB. The design offers at least 17 dB of isolation, amplitude unbalance within ±0.5–0.6 dB, and phase unbalance of ±6–8 degrees. Rated for 10 watts CW input and 0.1 A DC per port, it comes in a compact aluminum housing weighing 80 g (2.8 oz), is RoHS3 compliant and REACH unaffected, and is intended for indoor environments from −55 to +85 °C.
