Abstract

A klystron has been developed as a transmitting tube for earth stations of transportable or mobile type. The klystron, rather than the TWT, was chosen to make the transmitter compact. It has five cavities and mechanical pre-set tuners to cover the frequency range of 14.0 ~ 14.5 GHz and employs the permanent magnet focusing. Experiments have shown that a satisfactory performance was obtained at 2kW operation with a 50 MHz instantaneous bandwidth.
用于广播卫星系统地面站的14GHz 2kW速调管
研制了一种速调管作为可移动或移动式地面站的发射管。选择速调管而不是行波管是为了使发射机更紧凑。它有5个空腔和机械预设调谐器,覆盖14.0 ~ 14.5 GHz的频率范围,采用永磁聚焦。实验结果表明,该系统在2kW、50mhz的瞬时带宽下具有良好的性能。
