Power combiner used to combine the power from various solid-state amplifiers. A power combiner is essential for applications that require a larger power source for their efficient operation. Since taking inputs from multiple solid-state amplifiers is a tedious job and limits its overall power throughput. This paper proposes a design for 8:1 RF combiner, operating at radio frequency, which combines the power received at its eight input ports in one-step. The design approach is Circuit level combining based on N-way combining structure and radial combining and is analyzed using S-parameters. The simulated results show that this approach of designing 8:1 way power combiner provides a high degree of isolation, low return loss and low reflection loss with 90% efficiency and unsurpassed simplicity in design to fabricate.
