Ku waveband high-power narrow-pulse amplifier for fuse

The invention discloses a Ku waveband high-power narrow pulse amplifier for a fuse. The power amplifier comprises an input isolator, a driving power amplifier, an intermediate isolator, a final-stagepower amplifier, an output isolator, a GaAs modulation circuit, a GaN modulation circuit and a negative voltage protection circuit. The GaAs pulse modulation circuit (6) and the GaN pulse modulation circuit (7) are used for modulating externally input voltage into required TTL levels to supply power to the driving power amplifier (2) and the final-stage power amplifier (4) respectively. Accordingto the Ku band high-power narrow-pulse amplifier, under the test conditions that the pulse width of a power amplifier switch pulse signal is 100ns and the period is 1us, the peak output power in a full-temperature range is not less than 60W, and the output detection pulse width is greater than 80ns. 本发明公开了一种用于引信的Ku波段高功率窄脉冲放大器；包括输入隔离器、驱动功放、中间隔离器、末级功放、输出隔离器、GaAs调制电路、GaN调制电路、负压保护电路。所述GaAs脉冲调制电路(6)和GaN脉冲调制电路(7)用于将外部输入的电压调制成所需要
