Ceramic DLFCN-290+ Differential Low Pass Filter 50 DC to 290 MHz The Big Deal Differential operation Generic photo used for illustration purposes only CASE STYLE: FV1206-1 Small size Very wide stopband up to 2000 MHz Product Overview Mini-Circuits DLFCN-290+ is a LTCC dual low pass filter with a passband from DC to 290 MHz. This can operate as balanced input / output filter. This model is ideal for applications requiring filtering of balanced sig - nals on dual 50 lines such as DACs/ADCs, systems with very low noise requirements and more. The filter provides low insertion loss in the passband, and a very wide stopband up to 2000 MHz, making it suitable for use in wideband systems with many harmonics and spurious products. The unit comes housed in a tiny, rug- ged 1206 ceramic package, with wraparound terminations for excellent solderability. Key Features Feature Advantages Allows filtering of balanced signals in a single, tiny component. Eliminates the need for Differential filter binning and matching of separate discrete components. Tiny size (0.126 x 0.063 x 0.035 ) Saves space in dense circuit board layouts and minimizes the effects of parasitics. Provides excellent rejection over a wide band, ideal for blocking harmonics in wide- Wide stopband band communications systems. Wrap-around terminations Provides excellent solderability and easy visual inspection. Notes A.
