Title:
SYSTEM AND METHOD FOR CALIBRATING BALANCED SIGNAL
Document Type and Number:
Japanese Patent JP2004309472
Kind Code:
A
Abstract:
To calibrate balanced signals so as to create appropriate phases with respect to desired phase settings.
The electric power difference between the balanced signals is measured. A level acquired as a result is used to control the phase between the signals. In one form of implementation, I- and Q-inputs to a vector modulator are adjusted for controlling the phases.
