Multilayer Organic (MLO®) Filters

Richardson RFPD Inc. announced the availability and full design support capabilities for a lineup of multilayer organic filters from KYOCERA AVX. KYOCERA AVX’s MLO filters utilize high dielectric constant and low loss materials to realize high Q passive printed elements, such as inductors and capacitors, in a multilayer stack. The filters can support a variety of frequency bands and multiple wireless standards and are less than 1.0 mm in thickness. All filters are expansion-matched to most organic PCB materials, resulting in improved reliability over standard silicon and ceramic devices.
