A 14GHz 2kW Klystron for Earth Stations of Broadcasting Satellite Systems

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.
