| Abstract: | A Wideband 4-Way In-phase Power Combiner at 3 MHz～30 MHz has been introduced based on the Transmission line transformer theory.By using software simulation its operating frequency range of the transmission characteristics,loss characteristics,phase shifts are analysed.On the basis of circuit this power combiner was finished.The port range of the power combiner has the imbalance of the amplitude<±0.4 dB,as well as the phase<±5°,the VSWRs<1.5,isolations>19 dB.From above testing data,this combines is very suitable for high-power. |
