A variable impedance circuit comprises a transistor for varying impedance, a resistor connected between the collector and base of the transistor, a diode connected to the base of the transistor with a polarity opposite that of an equivalent diode between the base and emitter of the transistor, and a variable voltage source for control connected to the diode and operating to vary voltage. The impedance between the collector and ground of the transistor is varied with excellent linearity in accordance with the value of the voltage of the variable voltage source.
