N2 - In this paper, a power divider is suggested for predefined positive and negative group delay characteristics. The positive group delay (PGD) is obtained in between transmission paths 2 and 1, whereas the negative group delay (NGD) is in between transmission paths 3 and 1. The PGD and NGD are controlled by characteristic impedance of horizontal transmission line Z1 and shunt resistor R. Perfect input and output matching characteristics as well as perfect isolation are obtained at a center frequency (f0). For an experimental demonstration, microstrip line power divider with the PGD and NGD of 0.6 and -0.5 ns, respectively, was designed and fabricated at f0 of 2.14 GHz. The measurement results are agreed well with simulation results and theoretical predicated values.
