RFMW announced availability of the Knowles (DLI) portfolio of broadband SMD filters. The portfolio uses patented ceramic substrate with materials exhibiting excellent temperature stability and high K factors. Combined, these characteristics enable small size with high performance. For example, the B259MC1S is a 24.25 to 27.5 GHz bandpass filter with a typical insertion loss of 2.9 dB. Measuring 5.5 x 2.3 x 1.8 mm, this surface mount filter offers up to 30 dB out-of-band rejection. Catalog devices come complete with integrated shielding and the surface mount versions are designed for use on most RF PWB materials. Evaluation boards are available for qualifying programs.
