NOVEL LOW NOISE AMPLIFIER ARCHITECTURE FOR CARRIER AGGREGATION RECEIVERS

摘要

A low noise amplifier includes a first input transistor coupled to an input signal and a second input transistor coupled to the input signal. The low noise amplifier also includes a first output transistor, coupled between the first input transistor and a first carrier aggregation load, configured to connect the first input transistor to the first carrier aggregation load. Additionally, the low noise amplifier includes a second output transistor, coupled between the first input transistor and a second carrier aggregation load, configured to connect the first input transistor to the second carrier aggregation load. Further, the low noise amplifier includes a third output transistor, coupled between the second input transistor and the second carrier aggregation load, configured to connect the second input transistor to the second carrier aggregation load. Also included are a method of operating a low noise amplifier and an extended carrier low noise amplifier.
