Abstract
A dual directional coupler includes a housing, a main conductor, a forward coupled conductor and a reverse coupled conductor. The main conductor, the forward coupled conductor and the reverse coupled conductor are arranged in parallel within the housing such that the main conductor and the forward coupled conductor define a first two section quarter wave directional coupler, and the main conductor and the reverse coupled conductor define a second two section quarter wave directional coupler.
