Abstract
A waveguide bi-directional amplifier module is illuminated by a downstream illumination source and an upstream illumination source. The illumination sources are coupled to an array having waveguide to microstrip converters that provide for upstream and downstream electrical signals. Switchable amplifiers provide for amplification in both directions for the electrical signals and the converters coherently combine the output of the amplifiers to provide increased power to the electromagnetic wave entering the waveguide.
