The BFCQ-2702+ is an LTCC Band Pass Filter designed for miniature size and high performance repeatability. It utilizes a proprietary LTCC material system and distributed filter topology, offering a typical passband loss as low as 1.5 dB across the 22.0 31.0 GHz range. The filter provides typical stopband rejections of 43 dB up to 48 GHz, handles up to 1W RF input power, and operates within a wide temperature range of -55 to +125C. This filter ensures repeatable performance on a lot-to-lot basis.
