DLI Portfolio of Broadband SMD Filters

July 12, 2021

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.
