Abstract
PURPOSE:To suppress deterioration in transmission by compensating amplitude inclination due to a coaxial cable, by constituting a device so that the polarity of a signal frequency-converted at a transmission part can be set oppositely to that of the signal frequency-converted at a reception part. CONSTITUTION:A transmission side is provided with a modulation part 1 and the transmission part 2, and those parts are connected by the coaxial cable 3, and also, a microwave is outputted from an antenna 4. Also, a reception side is provided with an antenna 5, the reception part 6, and a demodulation part 7, and connects those with the coaxial cable 8. In such a case, a local oscillatory frequency in the transmission part 2 is set differently from that in the reception part 6. And the polarity of the signal frequency-converted at the transmission part 2 is set oppositely from that of the signal frequency- converted at the reception part 6, and by passing the signals with opposite polarity with each other through the cables 3 and 8, the amplitude inclination due to the cables 3 and 8 can be offset. Therefore, it is possible to compensate the amplitude inclination in spite of difference in the kind or the length of the coaxial cable, and to suppress the deterioration in the transmission.
