Mini-Circuits VXHF-482M+ & VXLF-172H+ Reflectionless Filters

Mini-Circuits VXHF-482M+ and VXLF-172H+ Reflectionless Filters employ a novel filter topology that absorbs and terminates stop band signals internally rather than reflecting them back to the source. This capability enables unique applications for filter circuits beyond those suited to traditional approaches. Mini-Circuits VXHF-482M+ and VXLF-172H+ Reflectionless Filters eliminate stop band reflections, allowing them to be paired with sensitive devices and used in applications that otherwise require circuits, such as isolation amplifiers or attenuators.
