Wireless communication device for transceiving heterogeneous radio-frequency signals
First Claim
1. A wireless communication device, comprising:
- a first antenna, for transceiving a first radio-frequency (RF) signal according to a first wireless communication standard;
a first transceiver, connected to the first antenna through a first transceiving path;
a second antenna, for transceiving a second RF signal according to a second wireless communication standard; and
a second transceiver, connected to the second antenna through a second transceiving path, wherein the second transceiving path comprises;
a reception path, electrically connected to the second transceiver and the second antenna, comprising;
a first RF switch;
a second RF switch, electrically connected to the first RF switch; and
an attenuator, electrically connected to the first RF switch and the second RF switch,wherein the wireless communication device reduces sensitivity for receiving the second RF signal in a joining process when establishing a connection to an end device according to the second wireless communication standard, wherein,in the joining process, the first RF switch conducts to the second RF switch through the attenuator; and
in a period other than the joining process, the first RF switch conducts to the second RF switch directly.

Abstract
A wireless communication device for transceiving heterogeneous radio-frequency (RF) signals is provided. The wireless communication device includes a first antenna, a second antenna, a first transceiver, a second transceiver and a controller. The first transceiver controls the first antenna through a first transceiving path to transceive a first RF signal according to a first wireless communication standard. The second transceiver controls the second antenna through a second transceiving path to transceive a second RF signal according to a second wireless communication standard. In a joining process when the wireless communication device establishes connection to an end device according to the second wireless communication standard, the controller reduces transmission power for transmitting the first RF signal, or reduces sensitivity for receiving the second RF signal.
