Abstract
This application provides a phased array apparatus and a communication device, and relates to the field of communication technologies. The phased array apparatus includes phased array channels coupled to antenna units in an antenna array. Each of the phased array channels is configured to transmit radio frequency signals of at least two frequency bands. Each of the phased array channels includes an intermediate frequency phase shifter configured to set a phase of an intermediate frequency signal corresponding to a radio frequency signal transmitted in the phased array channel.
