Abstract
A linearizer is provided which is capable of scaling its circuit down and making it lightweight, of lowering power consumption and of facilitating an input-output calibration. The linearizer is so configured that a first resistor is connected in series to a second resistor, a third resistor is connected to a connecting point between the first and second resistors, an FET (Field Effect Transistor) as a variable resistance element is connected to the third resistor, an inductor is connected between the FET and a GND, and the first, second and third resistors and the FET constitute a T-type attenuator.
