The ST4079 is a 50 Ohm RF termination, or dummy load, designed to absorb incident energy in unused ports with minimal reflection. It operates across a wide frequency range from DC to 40 GHz with a maximum VSWR of 1.6:1. This component features a Mini SMP female coaxial interface and can handle a maximum continuous wave (CW) input power of 0.25 Watts. The ST4079 is ideal for ensuring signal integrity in applications such as test and measurement, wireless and satellite communications, and radar systems.
