LTCC SURFACE MOUNT Bandpass Filter 50Ω BFHK-1742+ 16 to 19 GHz THE BIG DEAL y Ultra-High Stopband Rejection, Typ. 85 dB y Standard Small 1812 (4.5mm x 3.2mm) Case Style y Rugged Ceramic Construction y Protected by US Patents 11,638,370 and 11,744,057 Generic photo used for illustration purposes only FUNCTIONAL DIAGRAM RF1 RF2 1 2 APPLICATIONS y Test & Measurement Equipment y Aerospace and Defense Signal Conditioning 3 3 PRODUCT OVERVIEW The BFHK-1742+ LTCC Bandpass Filter achieves a miniature size and highly repeatable performance by utilizing a proprietary LTCC material system and distributed filter topology. The passband loss between 16.0 – 19.0 GHz is typically 2.9 dB, with typical stopband rejection of 85 dB up to 11.5 GHz and 70 dB up to 40 GHz. This model handles up to 1 W RF input power and has a wide operating temperature range from -55°C to +125°C. KEY FEATURES Features Advantages Ultra-High Rejection Typical stopband rejections of 85 dB up to 11.5 GHz and 70 dB up to 40 GHz. LTCC Construction The use of LTCC technology allows for repeatable performance in a rugged ceramic package, well suited for tough environment with high humidity and temperature extremes. See Mini-Circuits Environmental Rating ENV06T12 for more information. Cost Effective LTCC is a scalable technology that is cost effective due to its ease of production in high quantities. Small Size 1812 (4.5 mm x 3.2 mm) Allows for highly dense circuit board layouts, while minimizing the effects of parasitics. Surface Mountable Suitable for very high-volume automated assembly processes. REV. OR ECO-022153 BFHK-1742+ MCL NY 240620 www.minicircuits.com P.O.
