Abstract
A broad band frequency divider in which microstrip or stripline transmission lines and more than one microwave varactor diodes are interconnected to form a circuit which is resonant at a frequency of one-half of the input signal frequency and whose output consists substantially of odd order harmonics of one-half of the input frequency, the even order harmonics being virtually eliminated. An unbalanced output signal is achieved through the use of a coplanar balun. An optional DC external bias may be applied to the varactor diodes.
