Abstract
Wireless communications devices, methods and systems are implemented in various fashions. According to one such implementation, a method is used in a device using time-division-multiple access and multiple-mode wireless modules. Logic generates a signal indicative () of a first (e.g., TV) wireless module () being active. In a first state where the first wireless module () is active, a switch connects a transmitter of a second (e.g., cellular) wireless module () to a duplexer (). In a second state where the first wireless module is not active, logic connects the transmitter of the second wireless module () to an antenna () while bypassing the duplexer (). Logic connects, in the first state, the duplexer () to the antenna () and connects, in the second state, the transmitter to the antenna while bypassing the duplexer (). The duplexer () connects a receiver of the second wireless module () to the antenna () and includes a transmit band pass filter designed with a rejection band near an operating band of the first wireless module ().
