VECTOR MODULATOR

摘要

PURPOSE: A vector modulator is provided to attenuate the signal distributed by a broadband power distributor using the broadband variable attenuator. CONSTITUTION: At least one variable attenuator(12) controls the attenuation constant value by changing the internal resistance value according to the voltage value of a pin diode. The variable attenuator controls the attenuation value of an input periodic signal by controlling the attenuation constant value.
