N2 - This paper presents group delay investigation and implementation of unequal power divider with very high power division ratio. The proposed structure consists of Wilkinson power divider and branch-line where direct and coupled ports are terminated with resistors. By analytically study, the group delay associated with transmission paths between 3 and 1 is negative whereas the group delay associated between transmission path 2 and 1 is positive. Moreover, the negative group delay (NGD) characteristics are purely controlled by resistor connected in branch-line. For experimental validation, the power divider with power division ratio of 21.39 dB and NGD of-0.529 ns was designed, fabricated and measured at center frequency of 2.14 GHz.
