16 ways X-band wilkinson power divider for phased array transmitter

A 1:16 Wilkinson power divider on microstrip line is presented and analyzed used as a feed line for phased array transmitter. A 1:2 power divider in X-band (8-12 GHz) is cascaded to design 16 ways power divider which divides the power equally at each output port. It is cavity based divider designed on Rogers 4350B substrate and has size 208mm × 78 mm × 10mm including cavity without connectors. This divider provides good impedance matching at all ports, good phase and amplitude consistency between the output ports. The divider presented in this paper has Isolation better than 15dB, insertion loss less than 15.2dB and VSWR less than 2 as represented in both measured and simulated results.
