High-power radial combiners play an indispensable role in the field of microwave and space technology, serving as crucial components in communication and military radar systems. These intricate devices are pivotal for combining power from multiple input sources into a singular high-power output signal. The categorization of power combiners encompasses various variables, including power combining methodology, combining medium, port count, power-handling capacity, size, and combining stages. Our innovative design eliminates the need for small gaps near the feeder line, allowing us to achieve both high-power handling and full-band operation. This design results in exceptional performance, including amplitude and phase balances within ±0.4 dB and ±3° degrees. The 8-way high-power coaxial radialcombiner’s remarkable return loss exceeds 18dB, ensuring an impedance bandwidth beyond 40%. It can handle power outputs exceeding 450 KW, marking a significant advancement in radial combiner technology.
