Abstract


Matched load in the microwave transmission system is an important component , it is related to the system's transmission efficiency , high power capacity and working stability , related to the microwave measurement system errors and measurement accuracy , and the microwave components quality issues. Therefore, the load is very important in microwave technology , microwave systems is an important aspect. Traditional water load because of its structural deficiencies make it increase power capacity and reduce VSWR aspects difficult to get better development , making the water load in broadband high-power research has not kept pace the development of high-power microwave systems needs. In this paper, a radiation- type water load was studied , developed a wide-band high-power double-ridged waveguide water load. This double-ridged waveguide affecting water load matching the four factors, including the shape of the water chamber , double-ridged waveguide miter angle , dielectric plate materials as well as the thickness of the dielectric plate are using high frequency simulation software MWS CST simulation, according to the simulation results and the actual conditions into account to determine the parameters of the final processing and assembly into a kind . Load this water temperature were carried out at room temperature (20 ℃), 30 ℃, 40 ℃ and 50 ℃ VSWR test , test results are satisfactory and in power for good use . This water then introduced in high-power load conditions using the program . Finally this water as a high-power microwave power meter load case made ??use of the program .
