BFHKI-9901+ is a miniature low temperature co-fired ceramic (LTCC) ultra-high stopband rejection band pass filter with a 8.6 to 10.9GHz passband that supports a variety of applications. This model achieves 35dB typical stopband rejection up to 23.4GHz, when mounted on coplanar waveguide layouts. Housed in a small 4.95mm by 3.65mm 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 3.7dB typical insertion loss over a wide band 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.
