RFMW announces availability of a portfolio of broad-band SMD filters from Knowles (DLI). The portfolio is comprised of ceramic substrate filters using patented materials which exhibit excellent temperature stability and high K factors. Combined, these characteristics enable small size with high performance. Supporting general purpose and T&M applications, popular bandwidths include 2 to 4 GHz, 4 to 8 GHz, 8 to 12GHz and 12 to 18 GHz. For example, the B096QC2S, 8 to 12 GHz filter measures just 10.1mm x 4.6mm x 2.5mm while offering 2.5 dB typical insertion loss with 50 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.
