It has a structure in which a received signal is extracted through a small coaxial connector 62.

This is because the characteristics of each low-noise converter 63 cannot be directly measured.
In this case, the coaxial connector 52.

実施例
本発明の一史施例を図面にもとずｌＡで説明する。As mentioned above, the present invention does not use a low-noise converter that uses a coaxial connector as an input structure, as in the conventional example, so the loss due to the coaxial connector, which cannot be ignored in the 120th band, is reduced by the acid loss. For microwaves such as the 71 band, waveguides have much lower transmission loss than coaxial, cable, or cables. L Example History of the present invention This will be explained based on the drawings.
