Title:
PHASED ARRAY APPARATUS, COMMUNICATION DEVICE AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2023/159649
Kind Code:
A1
Abstract:
The present application relates to the technical field of communication, and provides a phased array apparatus and a communication device, for use in realizing the phase synchronization of a plurality of chips when the plurality of chips are stitched to form a phased array, and reducing a phase error among the plurality of chips while reducing costs. The apparatus comprises a first power divider, a first chip, a second chip, a third chip and a fourth chip; a local oscillator output end of the first chip is coupled with an input end of the first power divider; two output ends of the first power divider are respectively coupled with a local oscillator input end of the second chip and a local oscillator input end of the third chip; a local oscillator output end of the second chip is coupled with a local oscillator input end of the first chip; a local oscillator output end of the third chip is coupled with a local oscillator input end of the fourth chip; the local oscillator output end of the first chip is used for outputting a local oscillator signal, the local oscillator signal being used for realizing the phase synchronization of the plurality of chips.
