A high frequency phase generator comprising an oscillator, operating at eight times the desired frequency. A first set of flip-flop circuits divides the frequency down to the desired frequency. A second set of flip-flop circuits is provided with clock signals at the oscillator frequency and is connected so that the first flip-flop circuit of the second set is fed by the output of the first set and each subsequent flip-flop circuit in the second set is fed by the output of the preceding flip-flop circuit. Due to timing differences resulting from the two different frequencies, each flip-flop circuit in the second set produces two outputs which are 180 DEG out of phase with each other and 45 DEG out of phase with the outputs of the adjacent flip-flop circuits.
