Abstract
Official abstract text for this publication.
A wireless communication apparatus of the present invention comprises a switching unit, provided between a transmitting circuit and/or a receiving circuit of at least one communication system and a demultiplexer, for connecting the transmitting circuit and/or the receiving circuit of the communication system to antenna either directly or by way of the demultiplexer. When a communication system having the switching unit is solely operated, the transmitting circuit and/or the receiving circuit of the operating communication system is connected directly to the antenna without the demultiplexer. Therefore, it is possible to reduce insertion loss of the circuit and thus to improve receiving sensitivity and reduce power consumption.
First claim
