Abstract

PURPOSE:To ensure the comensation for lowering of the amplitude characteristics of the low frequency band by connecting the delay equalizer circuit, in which the change of the fluctuation property of the delay amount features the opposite polarity to each other against the reception and transmission frequencyes and with nearly the same inclination, between the connection circuit and the frequency converter circuit. CONSTITUTION:Reception amplifier circuit 6 amplifies the reception signal of reception frequency fR and deviates the reception output by a fixed deviation frequancy via frequency converter circuit 10 to form the transmission signal of transmission frequency fT. With this output, transmitter circuit 12 is amplified for transmission. Then delay equalizer circuit 9 and 9', in which the fluctuation property of the delay amount features the opposite polarity to each other a gaist the frequency fR and fT and with nearly the same inclination, are provided between branch connection circuit 7 and circuit 10. As a result, the lowering of the amplitude characteristics can be compensated at the low frequency band.
