摘要： 2.1 It is an object of the present invention to downconvert SHF signals, especially in the 22 GHz band, by means which are already on the market and not too expensive.
2.2 According to the invention the SHF signals are double converted or a subharmonic mixer can be used.
2.3 The invention can preferably be used for 22 GHz DBS systems.

摘要翻译： 2.1本发明的一个目的是通过已经在市场上的手段对SHF信号，特别是在22GHz频带中进行下变频，而不是太昂贵。 2.2根据本发明，SHF信号是双重转换的，或者可以使用次谐波混频器。 2.3本发明可以优选用于22GHz DBS系统。
