Abstract :
Active d.c. directional couplers which are combinations of conventional transmission line attenuator networks and d.c. amplifiers are described. The circuits of and design equations for signal-detecting and signal-injecting directional couplers with responses which are inherently flat from d.c. to an amplifier-dependent upper frequency limit are presented.
