Abstract

A directional coupler cable 10 is provided which is capable of making a point-to-point connection to patch board arrangement 11 and is further capable of providing a signal coupling thereto. The cable coupler 10 comprises a main transmission line conductor 12 which runs from one connector end to the other of the cable and is located equidistant between and parallel to a first and second coupling conductor 14,16. The first coupling conductor 14 is a stub line conductor connecting the main transmission line 12 to a peripheral device. The second coupling conductor 16 has a terminating resistance 18 located at one end thereof, opposite the end of the first coupling conductor 14.

Cable Coupler

A directional coupler cable 10 is provided which is capable of making a point-to-point connection to patch board arrangement 11 and is further capable of providing a signal coupling thereto. The cable coupler 10 comprises a main transmission line conductor 12 which runs from one connector end to the other of the cable and is located equidistant between and parallel to a first and second coupling conductor 14,16. The first coupling conductor 14 is a stub line conductor connecting the main transmission line 12 to a peripheral device. The second coupling conductor 16 has a terminating resistance 18 located at one end thereof, opposite the end of the first coupling conductor 14. A connecting conductor 20 is connected between the other opposite ends of the first and second coupling conductors 14,16 so that a pulse travelling in a given direction will couple in the opposite travelling direction to or from the stub line 14 or main transmission line 12. The stripline construction of the cable 10 has a very small square cross section and is sufficiently flexible to provide point-to-point connections. A male connector 22 is shown at each end of the directional coupler cable by means of which the selected point-to-point connection can be made. A connector 24 is provided for connecting the stub line 14 to a peripheral device.
