The BFHK-1942+ is a surface mount LTCC bandpass filter designed for the SATCOM Ka-Band downlink, operating from 17.7 to 21.2 GHz with a 50 Ω impedance. It features a compact 1812 SMT package measuring 4.5 mm x 3.2 mm, a typical insertion loss of 0.8 dB in the passband, and stopband rejection up to 58 dB. The filter operates from -55 °C to +125 °C and handles up to 10 W input power within the passband at +25 °C. It is bi-directional and complies with RoHS/REACH standards. The case style is NM1812C-3 with tin over nickel plating and is rated to environmental standard ENV164.
Mini-Circuits’ BFHK-1942+ is a high-performance bandpass filter designed for the SATCOM Ka-Band downlink, covering 17.7 to 21.2 GHz with exceptionally low insertion loss and high out-of-band rejection. This filter was designed with an advanced substrate integrated waveguide (SIW) topology to deliver waveguide-class selectivity and rejection in a compact, SMT LTCC package. This approach combines the low loss and high-Q performance of waveguide structures with the scalability and manufacturability of standard SMT components.
