Filed: 1992-07-31
Abstract: PURPOSE: To provide a signal changeover circuit and a signal-generating circuit, without distortion and with good linearity between input output signals at a high frequency and superior isolation between input and output signals. CONSTITUTION: In the case of providing an output of a signal from an output terminal OUT1 , a circuit connecting to a gate terminal of a transistor(TR) Q11 has a high impedance and a cut-off voltage deeper than a pinch-off voltage is given to a gate of a TR Q12 . A gate and a source of a TR Q11 (Q12 ) are connected by a resistor R11 (R12 ) (The resistance is lower than the impedance of TRs Q15 , Q16 , when the gate of the TRs Q11 , Q12 is driven to make the TRs Q11 , Q12 conductive.) and the TRs Q11 , Q12 have a depletion characteristic. Thus, in this case, the gate-source voltage of the TR Q11 is zero and the TR Q11 is conductive. Furthermore, the TR Q12 is cut off. In this circuit, since the gate-source voltage is zero or a prescribed voltage regardless of the state of the passing signal, self-modulation caused in conventional circuits is not generated.
