LTCC Bandpass Filter 50Ω BFCN-1855+ 1790 to 1920 MHz The Big Deal • • • • Small size 3.2mm x 1.6mm Pass band (1790-1920 MHz) Low Insertion Loss (2.0 dB typical) Sharp rejection peaks close to stop band CASE STYLE: FV1206 Product Overview The BFCN-1855+ LTCC Band Pass Filter is constructed with 12 layers in order to achieve a miniature size and high repeatability of performance. Wrap-around terminations minimize variations in performance due to parasitics. Covering 1855 MHz ±65 MHz, these units offer low insertion loss and good rejection. Key Features Feature Advantages Small Size (3.20mm x1.6 mm) Allows for high layout density of circuit boards, while minimizing affects of parasitics. Rejection peaks at harmonic frequencies Provides good rejection of signals at harmonic frequencies, for improved system performance. Wrap around termination Provides excellent solderability and easy visual inspection capability. LTCC construction Provides a rugged package that is well suited for tough environments including high humidity and high temperature extremes. Notes A.
