ABSTRACT:
A normalization circuit for preventing divergence of the normalizing voltage of a coupler used for diversity operation in a communication system includes: a phase detector for generating a phase detection signal corresponding to first and second phase differences of the signals received from first and second inputs; a normalizer including a reference voltage generator for normalizing the phase detection signal so as to alternatively output one of either a constant voltage value, or a reference voltage value in the event that the constant voltage value is less than the reference voltage value; a phase shifter for multiplying and adding output of the normalizer by and with the first and second phase differences; and an adder for adding the output of the phase shifter to the signals received from the second input.
