BFHKI-1982+ is a miniature low temperature co-fired ceramic (LTCC) ultra-high stopband rejection band pass filter with a 17.5 to 22.2 GHz passband supporting a variety of applications. This model achieves 35 dB typical stopband rejection up to 46.5 GHz, when mounted on coplanar waveguide layouts. Housed in a small 4.95 mm by 3.65 mm ceramic form factor, the filter is ideal for dense signal chain PCB layouts where it complements MMIC size and performance. The BFHKI family with integrated interposer board enables installation onto PCB layouts with automated manufacturing equipment. This model provides low insertion loss of typically 3.4 dB from 17.5-21 GHz and 4.3 dB from 21-22.2 GHz due to its rugged monolithic construction. The LTCC fabrication process assures minimal RF performance variation while delivering a product that is well suited for environmental extremes of high humidity and temperature.
