Abstract

The invention discloses a MIMO transceiver integrated circuit (IC)which includes a plurality of multiple band direct conversion transmitter sections, a plurality of multiple band direct conversion receiver sections, and a local oscillation generation module. Each of the plurality of multiple band direct conversion transmitter sections includes a transmit baseband module and a multiple frequency band transmission module. Each of the plurality of multiple band direct conversion receiver sections includes a multiple frequency band reception module and a receiver baseband module. The local oscillation generation module is operably coupled to generate the first frequency band local oscillation when the multiple band MIMO transceiver IC is in a first mode and operably coupled to generate the second frequency band local oscillation when the multiple band MIMO transceiver IC is in a second mode.

Description

technical field [0001] The present invention relates to wireless communication systems, and more particularly, to multi-band wireless communication. Background technique [0002] The communication system supports wireless and wired communication between a variety of wireless and / or wired devices. Such communication systems range from national and / or international cellular telephone systems, the Internet to indoor point-to-point wireless networks. Every communication system is built and works according to one or more communication standards. For example, a wireless communication system may conform to, but is not limited to, one or more and / or versions of the following standards, IEEE802.11, Bluetooth (BT), Advanced Mobile Phone Service (AMPS), Digital AMPS, Global System for Mobile Communications (GSM), Code Division Multiple Access Service (CDMA), Local Multipoint Distribution Service (LMDS), and Multichannel Multipoint Distributed System (MMDS). [0003] Depending on the...
