Mobile wireless communications device having a single bluetooth / wireless local area network antenna and associated methods

摘要

A mobile wireless communications device (10) includes a wireless local area network (WLAN) radio (14) configured to generate a WLAN transmit signal, and a Bluetooth radio (16) configured to generate a Bluetooth transmit signal. A circulator (24) is coupled downstream of an antenna (25). A transmit path couples the WLAN radio and the Bluetooth radio to the circulator such that the WLAN radio and the Bluetooth radio are capable of transmitting simultaneously. In addition, a receive path also couples the WLAN radio and the Bluetooth radio to the circulator such that the WLAN radio and the Bluetooth radio are capable of receiving simultaneously.
