Abstract
A diversity receiver system includes reception circuits connected to antennas for converting frequency of a received signal to a base band signal; a diversity branch comparison circuit for directing a base band signal to be used by comparing an intermediate frequency supplied through the reception circuit; a base band delay detection circuit for outputting a detection signal which is generated by a delay detection of the base band signal directed by the diversity branch comparison circuit; and a DPLL circuit for generating an internal clock by using the detection signal supplied from the base band delay detection circuit, thereby securing a stable reception and providing a diversity receiver system having a small circuit scale.
