ST1847 is an RF termination load (dummy load) designed to absorb incident RF energy with minimal reflection in RF, microwave, and millimeter wave systems. It operates across a frequency range from DC to 18 GHz and can handle up to 0.5 Watt continuous wave (CW) input power, with a maximum VSWR of 1.35:1 and 50 Ohm impedance. The termination features a gold-plated beryllium copper construction with SMP female coaxial interface and PTFE insulation, ensuring reliable performance and durability. ST1847 is commonly used to terminate unused ports on devices such as couplers, circulators, and switches, as well as in measurement systems to ensure signal integrity and prevent device damage from reflected energy.
