One of the key factors of satellite television receiving technology is to develop a combinatory Unit of converter, which can operate can operate stably, reliably and also can be produced economically.This paper first reviewed the general principle of frequeney mixing and discussed the charateristics of decimeter band converter in detail. Then a plan was proposed that mass-produced converter in ordinary Tvsets could be converted into converter combinatory units good for 714 MHz satellite television receiving...

One of the key factors of satellite television receiving technology is to develop a combinatory Unit of converter, which can operate can operate stably, reliably and also can be produced economically.This paper first reviewed the general principle of frequeney mixing and discussed the charateristics of decimeter band converter in detail. Then a plan was proposed that mass-produced converter in ordinary Tvsets could be converted into converter combinatory units good for 714 MHz satellite television receiving system, The results obtained through experiments were also theoreticaly analysed. Experiments showed the scheme to be practical and feasible, the simple converter combinatory unit also reliable, stable, economical and easily popularized.
