As part of development program for a high power co-axial transmission line component test facility, an existing traveling wave resonator based stand is modified to improve gain and ring return loss. The 10 dB directional coupler in the earlier replaced with 14 couple radio frequency ring. To achieve improved isolation loss, design equipped two broadside strip-lines tunable gap between them. Detailed optimization without setup performed using simulator Computer Simulation Technology Microwave...
The high-power radio frequency source for ion cyclotron heating and current drive of ITER tokamak consists two identical 1.5 MW amplifier chains. These chains will be combined using a wideband hybrid combiner with adequate coupling flatness, phase balance, return loss, isolation response to generate 2.5 (RF) power in the range 36 60 MHz. As part in-house development program at ITER-India, flatness loss/isolation better than 0.4 −25 dB, respectively, has been simulated. A detailed analysis...
