Abstract
A wireless communication base station sharing apparatus for sharing one antenna between a main system and a subsystem is provided. In the wireless communication base station sharing apparatus, a first signal combiner/distributor is connected to a transmission/reception signal line of a main system duplexer through a first port, distributes a signal received through the first port to second and third ports, combines the signals received through the second and third ports according to the phases of the signals, and provides the combined signal through the first port or a fourth port. A second signal combiner/distributor is connected to a transmission/reception signal line of a subsystem duplexer through a fifth port and the antenna through an eighth port, distributes a signal received through the fifth port to sixth and seventh ports, combines the signals received through the sixth and seventh ports according to the phases of the signals, and provides the combined signal through the fifth or eighth port. A first filter is provided in a signal path between the second port of the first signal combiner/distributor and the sixth port of the second signal combiner/distributor. A second filter is provided in a signal path between the third port of the first signal combiner/distributor and the seventh port of the second signal combiner/distributor.
