This study presents an unequal divider with asymmetric shunt open stubs to reduce circuit size and achieve harmonic suppression. The design method was derived from S- to admittance parameter conversion of unequal divider. We validated the use of the parameter conversion method to reduce the size and achieve harmonic suppression of the unequal divider by implementing the divider at a power ratio of 3 at a center frequency of 1 GHz. The measured characteristics agreed well with the results of the calculation and the harmonic suppression was improved by more than 14 dB between the 2nd and 4th harmonics with 20% reduction in size compared to a conventional divider.
