DLI Brand Bandpass Filters

DLI microstrip bandpass filters offer classical filter topologies yielding excellent performance in a small footprint when fabricated on ceramic substrate materials. Miniaturization can reach new levels by employing DLI high-k ceramic materials. Different techniques are employed to realize small size and high performance. Catalog devices come complete with integrated shielding and the surface mount versions are designed for use on most RF PWB materials. Typical features include center frequency from C to above Ka band although custom devices are avaliable from 1 to 60 GHz. Band pass filters pass desired frequency range and suppress the rest of undesired spectrum. Designed from 800MHz to 67GHz.

Temperature Stable: -55 to 125 degree C
Filter Size reduction: up to 20x using CG material, 10x using CF, 3 times using PG versus typical PWB
High Repeatability - Thin Film manufacturing provides precise manufacturing performance; no tuning
