Mini-Circuits’ High-Rejection Reflectionless Bandpass Filter Passes 15.5 to 16.5 GHz

Mini-Circuits’ XBF-163+ is a reflectionless band pass filter with a passband from 15.5 to 16.5 GHz.  The filter employs a patented filter topology, which absorbs and terminates stopband signals rather than reflecting them back to the source.  This capability eliminates stopband reflections typical of traditional filter designs, minimizing intermodulation and other interferences.  This model includes four sections, achieving stopband rejection up to 60 dB up to 30 GHz and 46 dB up to 40 GHz.  It provides 4.7 dB insertion loss in the passband, 1.4:1 passband VSWR, and 2.5:1 typical VSWR in the stopband.  It can handle RF input power up to 0.5W in the passband and 0.16W in the stopband, and it provides a wide operating temperature range from -55 to +105°C.  Fabricated using GaAs IPD process technology, the filter comes housed in a tiny 4x4mm QFN package.
