一、前言九十年代电子战系统将需要宽带、固态功率放大器,这种放大器能以较低的成本大量生产。该放大器将广泛应用于频率捷变、有源阵列雷达、雷达假目标、假目标转发器以及干扰发射机阵列。一般说来,这些放大器必须工作在10倍带宽的倍顿程带宽上,频率范围为2～20千兆赫,输出功率从数百毫瓦至数瓦。 I. INTRODUCTION The EW system in the 90s will need broadband, solid-state power amplifiers that can be mass-produced at a lower cost. The amplifier will be widely used in frequency agility, active array radar, radar false targets, false target transponders and interfering transmitter arrays. In general, these amplifiers must operate at an octave bandwidth of 10 times the bandwidth, with a frequency range of 2 to 20 GHz, with output powers ranging from hundreds of milliwatts to a few watts.
