BFHKI-1742+ is a surface-mount LTCC bandpass filter designed for 16 to 19 GHz signaling with 50Ω impedance. It features a compact 4.95 mm × 3.65 mm ceramic package with an integrated interposer board for automated pick-and-place assembly. The filter provides 3 dB typical insertion loss across its passband and achieves 66 dB typical stopband rejection up to 40 GHz. It operates reliably from -55°C to +125°C with a maximum input power of 1 W at +25°C, degrading linearly to 0.5 W at +125°C. Shielded construction and LTCC fabrication ensure stable performance in high-humidity and high-temperature environments. The part is RoHS compliant and marked with the identifier F559.
BFHKI-1742+ is a miniature low temperature co-fired ceramic (LTCC) ultra-high stopband rejection band pass filter with a 16 to 19 GHz passband that supports a variety of applications. This model achieves 66 dB typical stopband rejection up to 40 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 3 dB 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.
