The MOF2WS-27R is a surface-mountable, dual-layer, wideband RF passive device, designed to provide an impedance transformation across the HF to UHF frequency range. It features a series-stacked microstrip patch design, which supports high-power DC bias and balanced transmission, while maintaining high isolation between ports and low insertion loss. The device is capable of handling up to 3 W of power and provides excellent broadband performance. Its RoHS compliant gold plated copper body and copper ground plane provide superior thermal management for high power applications. The device is especially well suited for RF amplifier matching, antenna tuning, and radio system biasing applications.
