“…The front-end has been designed to conform to the specificiations of the Japanese system (4) Although optimised for the Japanese experiment, it is interesting to consider the front-ends performance in terms of the standards outlined by the 1977 WARC Conference (World Administrative Radio Conference) in order to evaluate its suitability for use with an eventual European Satellite. A comparison will therefore be made at the end of the paper for the two systems.…”

A 12 GHz receiver front-end has been designed and realised which uses field-effect transistors for each of the three major functions of r.f. preamplifier, mixer and local oscillator. In each of these functions, the FET presents its particular advantages of low noise figure as an amplifier, a conversion gain as a mixer and a relatively high efficiency as an oscillator. An overall noise figure of 4 dB should be possible in production quantities. The structure and overall system performance will be described.

“…However, as it is impossible to set up earth stations everywhere in the service area, earth stations which can be easily moved are very convenient. Therefore, transportable/mobile earth stations are planed and under construction in Japan [2]. In the transportable station whole electronic equipment is housed in a shelter, and the station is easily transported and assembled.…”

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.
