Title:
WIRELESS COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/082383
Kind Code:
A1
Abstract:
According to the present invention, a distributor (12) distributes a reception signal received by an antenna (11) into a first reception signal to be input to a BT/WLAN pass filter (13) and a second reception signal to be input to an LTE pass filter (20). An LTE detection unit (21) detects an LTE disturbance wave which passes through the LTE pass filter (20). When the LTE disturbance wave is detected by the LTE detection unit (21), a control unit (22) controls a switch (14) so that connections of a BT transmission amplifier (15), a BT reception amplifier (16), a WLAN transmission amplifier (17) and a WLAN reception amplifier (18) to the BT/WLAN pass filter (13) are to be off.
