ABSTRACT:
A wireless communication apparatus of the present invention has an interference signal cutoff circuit (10) for cutting off electric waves having interference frequencies of Δf=|frx±ftx| interposed between a receiving antenna (1) and a receiver (5). A transmitter (6) is connected to a transmitting antenna (11).In this way, provision of the interference signal cutoff circuit (10) makes it possible to prevent degradation of reception characteristics, the degradation being caused such that the transmission wave radiated from the transmitter (6) and input to the receiver (5), mainly via the receiving antenna1is modulated with interference waves by active elements provided in the receiver (5) to generate interference waves having the same frequency as the reception frequency frx.
