从对本体GaAs电子转移效应的广泛研究中,已发展起来一种新型的负阻器件。在连续波反射型放大器中应用此两端器件有可能提供几个倍频程瞬时带宽,约1瓦的输出功率和100分贝量级的线性动态范围。利用原型滤波器均衡网络的几种典型器件的应用特性和情况,有可能实现宽带放大器在C、X、K_u波段内工作,其带宽近4.0千兆赫,增益压缩为—1分贝时输出功率约为300毫瓦,饱和功率输出接近1瓦,噪声系数为15分贝。 From extensive research on the bulk GaAs electron transfer effect, a new type of negative resistance device has been developed. The use of this two-terminal device in a continuous wave reflective amplifier makes it possible to provide several octaves of instantaneous bandwidth, about 1 watt of output power and 100 dB of linear dynamic range. It is possible to realize wideband amplifiers operating in the C, X, and K_u bands by using prototype filters to balance the application characteristics and situations of several typical devices of the network. The output power is about 4.0 GHz with a gain-compression of -1 dB 300 milliwatts, saturated power output close to 1 watt, the noise figure is 15 dB.
