Ceramic Bandpass Filter 50Ω BFTC-615+ 450 to 780 MHz The Big Deal • LTCC construction • Temperature stable from -40°C to +85°C • Small size (0.150 x 0.150 x 0.059") CASE STYLE: FR933-1 Product Overview The BFTC-615+ LTCC bandpass filter covers the 450 to 780 MHz passband with 25 dB upper/lower stopband rejection. This model handles up to 3W RF input power and provides a wide operating temperature range from -40 to +85°C. Utilizing LTCC multi-layer construction, the filter achieves excellent repeatability of performance and comes in a tiny ceramic package saving space in dense PCB layouts. Key Features Feature Advantages LTCC Construction Provides a rugged package well suited for tough environments such as high humidity and temperature extremes. Tiny size (0.150 x 0.150 x 059”) Saves space in dense circuit boards and minimizes the effects of parasitics. Wide operating temperature range, -40 to +85°C Enables reliable performance in extreme environments Notes A.
