Mini-Circuits’ High-Rejection Reflectionless Bandpass Filter Passes 19.5 to 20.5 GHz

Mini-Circuits’ XBF-24+ is a reflectionless band pass filter with a passband from 19.5 to 20.5 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 rejection of 66 dB in the lower stopband and 55 dB in the upper stopband.  It provides 5.0 dB insertion loss in the passband and typical VSWR of 2.1:1 in the passband, 1.2:1 in the lower stopband and 2.2:1 in the upper stopband.  The filter 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
