Method and apparatus for wireless communicationdevice multiband tunable radio architecture

A method comprising:

• transmitting wireless communication signals from a multiband transceiver;
• receiving wireless communication signals for the multiband transceiver;
• providing low insertion loss in a transmit band and attenuation at a receive frequency using a tunable transmit notch filter coupled to the multiband transceiver;
• providing transmit to receive isolation using a tunable circulator coupled to the tunable transmit notch filter;
• and
• providing low insertion loss at a receive frequency and attenuation at other frequencies using a tunable receive filter coupled to the multiband transceiver.

A wireless communication device comprising:

• a multiband transceiver configured to transmit and receive wireless communication signals;
• a tunable transmit notch filter coupled to the multiband transceiver, the tunable transmit notch filter providing low insertion loss in a transmit band and attenuation at a receive frequency;
• a tunable circulator coupled to the tunable transmit notch filter, the tunable circulator providing transmit to receive isolation, the tunable circulator providing transmit signals from the multiband transceiver to an antenna via the tunable transmit notch filter;
• and
• a tunable receive filter coupled to the multiband transceiver, the tunable receive filter providing low insertion loss at a receive frequency and attenuation at other frequencies,
• wherein the tunable circulator provides receive signals from the antenna to the multiband transceiver via the tunable receive filter.
