Mini-Circuits BFCN-8000 LTCC Band Pass Filter Offering High Signal Rejection and Compact Size for Layouts
Product Overview
The BFCN-8000+ LTCC Band Pass Filter is constructed with 5 layers to achieve a miniature size and high repeatability of performance. Wrap-around terminations minimize variations in performance due to parasitics. Covering 8000 MHz 100 MHz, these units offer low insertion loss and good rejection at the band reject edges. Its small size (3.20mm x 1.6 mm) allows for high layout density of circuit boards, while minimizing effects of parasitics. Rejection peaks close to the pass band provide good rejection of signals near the pass band for improved system performance. Wrap-around termination provides excellent solderability and easy visual inspection capability. LTCC construction provides a rugged package well-suited for tough environments including high humidity and high temperature extremes.
