Mini-Circuits’ XLF-272M+ reflectionless filter employs a novel filter topology which absorbs and terminates stopband signals internally rather than reflecting them back to the source. This new capability enables unique applications for filter circuits beyond the traditional approaches. Traditional filters are reflective in the stopband, sending signals back to the source at 100% of the power level. These reflections interact with neighboring components and often result in intermodulation products and other interferences. Reflectionless filters eliminate stopband reflections, allowing them to be paired with sensitive devices and used in applications that otherwise require circuits such as isolation amplifiers or attenuators.
