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. KEY FEATURES Features Advantages Surface mountable due to Integrated Interposer Board Enables installation with automated manufacturing equipment, making this suitable for high-volume processes. Wide Rejection Provides high stopband rejection of 35dB typical up to 23.4GHz. Small Size (4.95 x 3.65mm) Allows for high layout density of circuit boards, while minimizing effects of parasitics. Wide Operating and Storage Temperature (-55 to 125°C) Enables use in high reliability and extreme environment conditions, such as in aerospace & defense applications. Cost Effective LTCC is a scalable technology that is cost effective due to ease of production in high-volume. REV. OR ECO-018895 BFHKI-9901+ MCL NY 240308 www.minicircuits.com P.O.
