Abstract
According to one or more embodiments, a directional filter assembly () comprises a multi-port filter circuit () for combining or separating signals in specified pass-bands and an isolated port () having a resistive load (), for absorbing out-of-band signals. The assembly further includes a reflective protection device () configured to protect the resistive load () from being overpowered by out-of-band signal power, based on being configured to reflect or not reflect the out-of-band signals in dependence on the level of out-of-band signal power. In at least one embodiment, the directional filter assembly is configured as a microwave transmission assembly, such as is used for combining signals from two or more base stations, for transmission from a common antennae assembly.
