MICROWAVE-BAND WIRELESS TRANSMITTER, MICROWAVE-BAND WIRELESS RECEIVER, AND MICROWAVE-BAND WIRELESS TRANSMISSION/RECEPTION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a microwave-band wireless transmitter, microwave-band wireless receiver, and microwave-band wireless transmission/reception system that easily achieve excellent transmission characteristics having almost no interference even when two modulation signals wirelessly transmitted in a microwave band have the same frequency band.;SOLUTION: When a first modulation signal is frequency-upconverted to the microwave band by frequency mixers 201a, 301a, a first reference signal is added to the first modulation signal by a power synthesizer 202a so as to transmit a first wireless multiple signal by a transmission amplifier 303a and a transmission antenna 4a. When a second modulation signal is frequency-upconverted to the microwave band by frequency mixers 201b, 301b, a second reference signal having a frequency different from that of the first reference signal is added to the second modulation signal by a power synthesizer 202b so as to transmit a second wireless multiple signal by a transmission amplifier 303b and a transmission antenna 4b with a polarized wave different from that of the first wireless multiple signal.;COPYRIGHT: (C)2008,JPO&INPIT
