宽带大功率限幅器小型化研究

Research on wideband high-power limiter with small size

采用微波混合集成电路设计方法，用并联二极管和检波二极管，在很小的腔体内制作了无源微波限幅器。其电参数为：频率范围2．18GHz；承受功率4W（连续波）；限幅电平≤30mW（Pin为4W，连续波）；插入损耗为2．5dB以下：驻波系数为2．0以下。外形尺寸为13．5mm×6mm×3mm；输入输出端为50Ω绝缘子。

The microwave limiter modules were designed and fabricated with hybrid integrated circuit in a small size. It was fabricated with tow PIN diodes and a single detector diode chip. Its electric characteristics are： the frequency range 2-18 GHz, survival power 4 W, the leakage ≤ 30 mW, the insertion loss ≤2.5 dB, VSWR〈2.0. The package size is 13.5 mm×6 mm×3 mm and the connectors are 50 Ω pin.
