ABSTRACT:
A hyperfrequency dynamic divide-by-two frequency divider circuit includes an inverter stage A and a follower stage B, in which the output of the inverter stage is applied to the input of the follower stage via an interrupt transistor T.sub.1 which is controlled by the hyperfrequency input signal H having a frequency f.sub.e. The output Q of the follower stage B is fed back to the input of the inverter stage A and supplies the output signal having a frequency f=f.sub.e /2. The operation of the divider takes place subject to the conditions:
