摘要
针对海上短波广播的需要,提出了一种使用10m鞭天线和矢量天线调谐器的新型1kW大功率短波天馈系统。通过分析该系统的带宽和匹配网络结构,提出了矢量阻抗测量的方法,并给出具体的调谐算法。测试数据结果表明,该方法比传统天调的调谐速度快,调谐功率低,此短波广播天馈系统能完全满足研制要求。
For the request of the short-wave radio broadcasting in the ocean, a new type of antenna system consisting of a 1 kW power amplifier and 10 m whip antenna is proposed. By analyzing the bandwidth and structure of the matching net- work, a method for tuning via vector measurement of the antenna is proposed, which has a better performance than a tradi- tional method regarding the tuning rate and power consumption. The test data proves that the system fulfills the requirements.
