Abstract


With the development of power devices , vacuum devices and solid-state devices there is competition . As a result of the competition , a new type of microwave power devices , constituted by broadband miniaturized traveling wave tubes, power drive link and integrated power , microwave power module MPM been proposed. Having preferably excellent characteristics, able to meet the requirements of the next - generation power source . MPM composition , function and development trend of the power drive link , and the link structure of a power driver . The link consists of a solid state power amplifier , power control and stability circuit and microstrip power equalizer to the miniaturization of traveling wave tube drive power and gain balance . According to constitute the principle of the power of the equalizer , the power equalizer analysis, a practical design method . The method mainly resonant minor, impedance matching as the basic module to analyze the power equalizer . Finally, the optimization of the use of computer -aided design of balanced network , power equalizer can shorten the development cycle . According to the method proposed by the paper , power equalizer based on microstrip structure 0.8GHz-2GHz, 2GHz-8GHz, 6GHz-18GHz broadband within the power equalizer with low cost , small size , high integration features . According to the composition of the power drive link , a brief analysis the power equalization network design and measurement , the safety of the power chip assembly , use and protection of other methods . Based on this analysis , the 2GHz-6GHz power drive link . The link provides maximum gain ≥ 20dB, saturated output power ≥ 1W .
