【摘要】 本文研制了一款工作在74-80GHz频段内的六倍频放大模块,整个模块由有源六倍频器,功率放大器,带通滤波器,波导-微带过渡结构等组成。测试结果表明:在74-80GHz的输出频带内,典型小信号增益为24dB,输出P1dB压缩点为18.5dBm,饱和输出功率为21.6dBm,当输入功率为-4dBm时,输出功率平坦度小于4dB。设计完成的六倍频放大器级联230GHz三倍频器进行测试,在225-233GHz均能得到120uW以上的输出功率。最终级联170-260GHz可调衰减器实现了输出功率的连续可调。更多还原

【Abstract】 This paper design a frequency sextender amplification module working in the 74-80 GHz frequency band. The whole module consists of an active six-frequency multiplier, power amplifier, band-pass filter, waveguide-microstrip transition structure,etc.The measured results show that the typical small signal gain is 24dB, the output P1dB compression point is 18.5 dBm, and the saturated output power is 21.6dBm in the output frequency band of 74-80 GHz. When the input power is-4dBm, the output power flatness less than 4 dB. The designed frequency sextender amplification is used as the driving source of the 230GHz tripler,the output power is more than 120uW in the range of 225-233 GHz band,.Finally, the 170-260GHz adjustable attenuator is connected to realize the continuous adjustment of the output power.更多还原
