CROSS-CONNECTED CASCODE LOW NOISE AMPLIFIER FOR CARRIER AGGREGATION

摘要

An apparatus includes a first amplifier circuit (650a) and a second amplifier circuit (650b). The first amplifier circuit (650a) has a first output coupled to a first load circuit (670a) in a multi-output mode, and the second amplifier circuit (650b) has a second output coupled to a second load circuit (670b) in the multi-output mode. The apparatus further includes a first divert circuit (650d) and a second divert circuit (650c). The first divert circuit (650d) is configured to divert a first portion of a first amplified signal from the first amplifier circuit (650a) to the second load circuit (670b) in the multi-output mode. The second divert circuit (650c) is configured to divert a first portion of a second amplified signal from the second amplifier circuit (650b) to the first load circuit (670a) in the multi-output mode.
