Popis:	This paper described the design and fabrication of broadband 4-way power divider which has a phase difference between output ports in 20100 MHz VHF-band. A 4-way power divider was designed using 4-way in-phase power divider which consisted of three 2-way in-phase power dividers and two second-order all pass filters which gives phase difference between output ports. The measured insertion loss was less then 6.6 dB, return loss and isolation were better than 19 dB, and phase error between phase difference outputs was less than 1.
