We investigate by numerical simulation the behaviour of the power diss
ipated in a resistive load capacitively coupled to a Josephson flux-fl
ow oscillator and compare the results to those obtained for a d.c. cou
pled purely resistive load. Assuming realistic values for the paramete
rs R and C, both in the high- and in the low-T-c case the power is lar
ge enough to allow the operation of such a device in applications.
