The invention is a static frequency divider with a divider ratio which can be switched over, tor use in the extremely high frequency range. In a preferred embodiment, the invention is a static frequency divider with a divider ratio which can be switched over, which includes first and second divider D- type flip-flops which each have two inputs which can be alternately activated by way of control inputs, in order to prevent the occurrence of metastable conditions. This is accomplished by connecting the successive synchronous D-type flip-flops upstream of the two divider D-type flip- flops and the control inputs of the first and second divider D-type flip-flops are connected to separate change-over switching devices.
