Abstract
Spatial power-combining devices and, more particularly, spatial power-combining devices with improved isolation are disclosed. Spatial power-combining devices are disclosed that include a thin film resistor that is configured to provide improved signal isolation. The thin film resistor may be arranged within one or more amplifier assemblies of the spatial power-combining device to reduce signal leakage between the amplifier assemblies. The thin film resistor may be formed on a carrier substrate or the thin film resistor may supported by a surface of an amplifier assembly without a carrier substrate. Spatial power-combining devices are disclosed that include a radial arrangement of amplifier assemblies, and each amplifier assembly includes an antenna structure and a thin film resistor.
