Abstract: Example multi-band phased array are described. One example multi-band phased array includes a plurality of branches coupled to a plurality of multi-band antennas. Each of the plurality of branches includes a low noise amplifier and a power amplifier. The power amplifier and the low noise amplifier are configured to transmit and receive, in a time-sharing manner, a signal of a first frequency band and a signal of a second frequency band that are received by the multi-band phased array, and the first frequency band and the second frequency band are different and do not overlap. Each of the plurality of branches further includes a phase shifter, where the phase shifter is configured to perform phase shifting on the signal of the first frequency band, and the phase shifter is further configured to perform phase shifting on the signal of the second frequency band.
