BFCQ-2872+

CERAMIC Bandpass Filter 50Ω BFCQ-2872+ 27.5 to 30.0 GHz THE BIG DEAL y Standard small 1008 (2.5mm x 2.0mm) case style y Low Insertion Loss – Mid band 1.2 dB typical y Wide rejection band y Shielded construction preventing filter from de-tuning y Reduced footprint area by employing LGA (land grid array) y Surface mountable pick and place standard case style Generic photo used for illustration purposes only CASE STYLE: NL1008C-7 APPLICATIONS y Satellite Communications PRODUCT OVERVIEW The BFCQ-2872+ LTCC Band Pass Filter achieves a miniature size and high repeatability of performance by utilizing a proprietary LTCC material system and distributed filter topology. The typical passband loss at 27.5 –30.0 GHz is as low as 1.2 dB, with typical stopband rejections at 37 dB up to 55 GHz. This model handles up to 1W RF input power, and provides a wide operating temperature range from -55 to +125°C. Utilizing a proprietary LTCC material system and a distributed filter topology, this filter is able to achieve repeatable performance on a lot-to-lot basis. KEY FEATURES Feature Advantages Cost effective LTCC is scalable technology that is cost effective due to ease of production in high quantities. Small size (2.5mm x 2.0mm) Allows for high layout density of circuit boards, while minimizing effects of parasitics. Surface Mountable Suitable for very high volume automated assembly process. REV.
