TheDirectional couplers having perfect dk-ectivity and constant input impedance at all frequencies, and for all degrees of coupliig, are obtained by placing equal resistive loads at each of the four terminal pairs. It is directional, with the highest noise levels at an angle of 40 to 50 degrees from the direction of the exhaust flow. There is a supersonic potential core of exhaust flow, surrounded by mixing region. All measurements done with an hp 8753 ES.with the surrounding air. Directivity Note : The directivity is the difference in dB of the power output of the two coupled ports, when power is transmitted in a constant direction on the main-line.

The basic configuration of a single directional coupler is shown in figure. Publication: Nature Communications Vol.: 12ISSN: 2041-1723The basic directional coupler is a four port junction that is used in a wide variety of microwave systems to satisfy almost any requirement for sampling incident and reflected microwave power conveniently and accurately with minimal disturbance to the transmission line. This fundamental noise mechanism is expected to impact microwave noise (and pulse timing jitter) whenever solitons radiate into dispersive waves belonging to different spatial mode families. At the same time, pump noise reduction by as much as 36 dB is demonstrated.
