ATTENUATOR FOR COMPENSATING PHASE ERROR AND ATTENUATING METHOD THEREOF |
摘要 |
PURPOSE: An attenuator and an attenuating method thereof capable of compensating a phase distortion are provided to compensate the phase distortion of a signal which is generated by a level attenuation. CONSTITUTION: A first attenuation unit (11) attenuates and outputs a level of an input signal. A first phase distortion compensating unit (21) compensates a phase distortion of a signal which is generated by the attenuation of the first attenuation unit. The first attenuation unit includes a serial resistance and a shunting resistor. The first compensating unit includes a capacitor which is connected to the shunting resistor. The capacitor is connected to the shunting resistor in parallel. [Reference numerals] (11) First attenuation unit; (12) Second attenuation unit; (13) Third attenuation unit; (14) Fourth attenuation unit; (15) Fifty first attenuation unit; (16) Fifty second attenuation unit; (21) First phase distortion compensating unit; (22) Second phase distortion compensating unit; (23) Third phase distortion compensating unit; (24) Fourth phase distortion compensating unit; (25) Fifty first phase distortion compensating unit; (26) Fifty second phase distortion compensating unit |
