1. A multi-band phased array, comprising:
a plurality of branches coupled to a plurality of multi-band antennas, wherein each of the plurality of branches comprises a multi-band low noise amplifier configured to receive an inter-band carrier aggregation signal, the inter-band carrier aggregation signal comprises a first carrier signal located in a first band and a second carrier signal located in a second band, and the first band is different from and does not overlap the second band;
wherein the multi-band low noise amplifier of each of the plurality of branches comprises an input end, a first input matching network, a second input matching network, a first amplifier, and a second amplifier, the input end is coupled to the multi-band antenna and is configured to receive the inter-band carrier aggregation signal, the first input matching network is coupled between the input end and the first amplifier, and is configured to implement impedance matching for the first carrier signal to generate a matched first carrier signal, the first amplifier is configured to amplify the matched first carrier signal, the second input matching network is coupled between the input end and the second amplifier, and is configured to implement impedance matching for the second carrier signal to generate a matched second carrier signal, and the second amplifier is configured to amplify the matched second carrier signal; and
wherein each of the plurality of branches further comprises a phase shifter configured to perform phase shifting on the first carrier signal output by an output end of the first amplifier and configured to perform phase shifting on the second carrier signal output by an output end of the second amplifier.
