The divider/combiner based on substrate integrated waveguide (SIW) technology is designed and implemented with a double antipodal four-way tree type divider structure.For the purpose of convenient connection with other planar circuits,each port of the divider/combiner is connected with an SIW to microstrip transition.Within the frequency range of 9.3 to 12.3GHz,the measured return loss is below -13dB and transmission loss is better than -3.3dB.A four-way power amplifier at X-band is designed,fabricated and measured in succession.Measured results show that the combined output power at 1 dB compression is about 7.1W (continuous wave) at 10.4GHz.The power combining efficiency is higher than 60% over the interested frequency range of 8.9 to 12.3GHz and it can reach 73.6% at 9.5GHz.The results demonstrate that this technique can be applied to microwave and millimeter-wave power combining with solid-state power amplifiers.
