摘要
电子装备现已被大量应用,在如此复杂的电磁环境下高功率微波可导致接收机灵敏度下降甚至失效。为了满足高功率微波的防护需求,介绍了一种基于PIN二极管的小型化高功率微波限幅器,体积为34 mm×Φ9 mm。测试结果表明,在0.3~2 GHz频带内,该限幅器实现了小信号插损小于1 dB,输入输出驻波比小于1.5;可承受脉宽100μs,占空比0.1%,峰值功率超过1000 W,漏功率小于17 dBm。国内外尚无类似指标限幅器相关报导。该高功率微波限幅器体积小、频带宽、耐功率高,可大大提高接收机可靠性,具有广阔的应用前景。
Nowadays,electronic equipment has been widely used,thus high power microwave(HPM)may lower the sensitivity of receiver or even destroy it under such complicated electromagnetic environment.To meet the demand of protection of HPM attack,a miniaturized HPM limiter based on PIN diodes is introduced.The HPM limiter is fabricated by using thin film hybrid integrated circuit technology,in a 34 mm×Φ9 mm metal package.The test results show that the insertion loss is less than 1 dB at 0.3-2 GHz and the VSWR is better than 1.5.Capable of handling up to 100μs pulse width,0.1%duty cycle,and 1000 W incident power levels,the limiter allows less than 17 dBm leakage power to pass through.There are no reports of similar limiters at home and abroad.With small size,wide operating band and extremely high power tolerance,the HPM limiter can greatly improve the reliability of receiver and has broad application prospect.
