Abstract
Multiple-input multiple-output (MIMO) low noise amplifiers (LNAs) supporting carrier aggregation are disclosed. In an exemplary design, an apparatus (e.g., a wireless device, an integrated circuit, etc.) includes a MIMO LNA having a plurality of gain circuits, a drive circuit, and a plurality of load circuits. The gain circuits receive at least one input radio frequency (RF) signal and provide at least one amplified RF signal. Each gain circuit receives and amplifies one input RF signal and provides one amplified RF signal when the gain circuit is enabled. The at least one input RF signal include transmissions sent on multiple carriers at different frequencies to the wireless device. The drive circuit receives the at least one amplified RF signal and provides at least one drive RF signal. The load circuits receive the at least one drive RF signal and provide at least one output RF signal.
