New Reflectionless High Pass Filters Provide Passbands to 30 GHz in 2x2mm QFN Packages

12 January 2017Mini-Circuits has expanded our line of revolutionary reflectionless filters to support even more of your applications. Our XHF2-series of reflectionless high pass filters features 5 new models covering a variety of passbands up to 30 GHz. They provide RF input power handling as high as 1.26W and come housed in tiny 2x2mm QFN packages, giving designers flexibility to use the filters almost anywhere in their PCB layout.


Reflectionless filters employ 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 those suited to traditional approaches. Traditional filters are reflective in the stopband, sending signals back to the source at 100% power. These reflections interact with neighboring components and often result in intermodulation 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.
