Abstract
A wireless communication device includes a first transceiver operable according to a first radio technology and a second transceiver operable according to a second radio technology and operable concurrently with the first transceiver. The wireless communication device further includes an antenna configured to transmit radio transmissions of the second transceiver, and a filter circuit coupling the second transceiver with the antenna. The filter circuit includes a first frequency path and a second frequency path in parallel. The first frequency path passes a first set of frequencies of the radio transmissions and the second frequency path passes a second set of frequencies of the radio transmissions. One of the first frequency path or the second frequency path is configured to filter the radio transmissions of the second transceiver to remove signals corresponding to the one or more operating frequencies of the first transceiver from the radio transmissions of the second transceiver.
