Automatic step variable attenuator and radio communication device |
摘要 |
An automatic step variable attenuator includes: a step variable attenuator attenuating a received signal of an electric wave signal in an attenuation amount corresponding to a control signal in a step-like style; a detector disposed in parallel with the step variable attenuator for input of the received signal of the electric wave signal, and converting an electric power of the received signal thus inputted into an intensity signal representing an intensity of the received signal; and a comparator portion generating the control signal corresponding to a result of comparison for differences between the intensity signal obtained from the detector and plural threshold values, and outputting the control signal thus generated to the step variable attenuator. |
