WIRELESS COMMUNICATION DEVICE, A WIRELESS COMMUNICATION METHOD, AN ANTENNA DEVICE AND THE FIRST DUPLEXER, ESPECIALLY IN RELATION TO USING A MODULATION METHOD HAVING AN ENVELOPE COMPONENT SUCH AS A CDMA SCHEME

摘要

PURPOSE: A wireless communication device, a wireless communication method, an antenna device and the first duplexer are provided to reduce deterioration of an RSSI during a simultaneous transceiving process without decreasing a standby time, and to output a differential signal while reducing deterioration of a transmission signal. CONSTITUTION: The first antenna(101) is comprised. The first transmit device(104) outputs a transmission signal having the first frequency band. The first duplexer(102) comprises a single phase input terminal and an equilibrium output terminal in connection with the first antenna(101), transmits the transmission signal inputted to the single phase input terminal to the first antenna(101), and outputs a receiving signal having the second frequency band different from the first frequency band to the equilibrium output terminal as a differential signal. The first receive device(103) includes a circuit where a gain of the differential signal is higher than a gain of an identical phase component signal or loss of the differential signal is lower than the identical phase component signal.
