已研制出用于相控阵的L波段和X波段的正交场放大管,使用二次发射冷阴极以及控制电报,使该管由直流电源直接工作,这样就不需要大功率调制器,并且结构大大简化且很灵活。在大的多管系统中,这些管子有着特殊的重要性。工作原理业已介绍。L波段管的性能数据表明,在中心频率1200兆赫、带宽120兆赫范围内,峰值功率输出为150千瓦,增益为15分贝,效率为50％。管子的相位特性和噪声特性的测量技术业已讨论。偏离线性的相位为5～10°数量级,而在电压变化1％的情况下,相位灵敏度典型地为2°,在脉冲期间寄生输出低于信导输出,为30分贝以上。
The L-band and X-band orthogonal field amplifiers for phased arrays have been developed that use secondary emission cold cathodes and control telegrams to make the tube work directly from a direct current power supply, thus eliminating the need for a high power modulator and The structure is greatly simplified and flexible. These pipes are of special importance in large multi-pipe systems. Working principle has been introduced. Performance data for L-band tubes indicate a peak power output of 150 kW with a gain of 15 dB and an efficiency of 50% at a center frequency of 1200 MHz and a bandwidth of 120 MHz. Measurement techniques for the phase and noise characteristics of tubes have been discussed. The phase deviating from the linearity is in the order of 5 to 10 degrees and the phase sensitivity is typically 2 degrees at 1% voltage variation. The parasitic output is lower than the signal-to-signal output by 30 dB or more during the pulse.
