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

A mobile wireless communications device comprising:

• a wireless local area network (WLAN) radio configured to generate a WLAN transmit signal;
• a Bluetooth radio configured to generate a Bluetooth transmit signal;
• an antenna;
• a circulator coupled downstream of said antenna;
• a transmit path coupling said WLAN radio and said Bluetooth radio to said circulator such that said WLAN radio and said Bluetooth radio are capable of transmitting simultaneously, the transmit path comprising transmit power combiner configured to combine the WLAN transmit signal and the Bluetooth transmit signal into a combined transmit signal;
• and
• a receive path also coupling said WLAN radio and said Bluetooth radio to said circulator such that said WLAN radio and said Bluetooth radio are capable of receiving simultaneously;
• said circulator configured to configured to couple the transmit path to said antenna and couple the receive path to said antenna while at least partially isolating the transmit path from the receive path.

A method of making a mobile wireless communications device comprising:

• coupling a circulator downstream of an antenna;
• coupling a WLAN radio and a Bluetooth radio to the circulator via a transmit path such that the WLAN radio and the Bluetooth radio are capable of transmitting simultaneously;
• and
• coupling the WLAN radio and the Bluetooth radio to the circulator via a receive path such that the WLAN radio and the Bluetooth radio are capable of receiving simultaneously;
• wherein coupling the WLAN radio and the Bluetooth radio to the circulator via a transmit path includes configuring a transmit power combiner to combine the WLAN transmit signal and the Bluetooth transmit signal into a combined transmit signal.
