<P>PROBLEM TO BE SOLVED: To provide a transceiver module with a small noise factor in the reception system. <P>SOLUTION: A transceiver module includes: reflection signal level detection means for detecting a level of a first reflection signal received by a transmission/reception antenna transmitting a transmission signal and receiving the first reflection signal that has been reflected; a low-noise amplifier, connected to a reception antenna receiving a second reflection signal reflected correspondingly to the transmission signal, for amplifying the second reflection signal; and switching-means for inputting to a subsequent receiver the first reflection signal when the reflection signal level detection means detects a magnitude of the first reflection signal being larger than a predetermined value, or inputting to the receiver an output of the low-noise amplifier when the reflection signal level detection means detects the magnitude of the first reflection signal being smaller than the predetermined value. <P>COPYRIGHT: (C)2013,JPO&INPIT |
