Transmitter and receiver architecture for multi-mode wireless device

A multi-mode wireless communication device capable of concurrent wireless communications with a plurality of wireless communication systems, the device comprising:

• a multi-mode transceiver integrated circuit including a transmitter having a plurality of power amplifiers in parallel, each power amplifier configured to amplify signals in at least one distinct transmit band of one of the plurality of wireless communication systems, and a receiver having a plurality of Low Noise Amplifiers (LNAs) in parallel, each LNA configured to amplify signals in at least one distinct receive band of the plurality of wireless communication systems;
• and
• a multi-mode baseband portion configured to configure an operating mode of the multi-mode transceiver in a time multiplex manner to each of the plurality of wireless communication systems to-permit the concurrent wireless communications with the plurality of wireless communication systems,
• wherein the multi-mode baseband portion configures the operating mode of the multi-mode transceiver in part, by configuring a mutually exclusive transmit or receive mode of the multi-mode transceiver, and a local oscillator frequency.

A method of configuring a multi-mode wireless communication device, the method comprising:

• selecting a communication system from a plurality of supported wireless communication systems for which active communications are time division multiplexed;
• determining an operating mode for the selected wireless communication system from a predetermined time division multiplexing schedule based on a timing of a first of the plurality of supported wireless communication systems;
• configuring a multi-mode transceiver based in part on the operating mode by selectively deactivating at least one Low Noise Amplifier (LNA) from a plurality of LNAs in parallel, each LNA configured to amplify signals in at least one distinct receive band of the plurality of supported wireless communication systems;
• and
• operating in the operating mode for a predetermined period of time based on the predetermined time division multiplexing schedule.
