Design of Suspended Stripline Ultra-Wide Band Multipath Power Divider
In this paper, a four ways UWB power divider covering Ka band have been made based on UWB 180 de- grees phase inverter with suspended stripline structure. Test results indicate that in 25 - 40GHz frequency range, the typical value of return loss is 15 dB, the typical value of S21, S31, S41 and S51 is 8.2 dB with an additional insertion loss of 2.2dB, and the isolation is larger than 18dB.
