Abstract: A device implementing the subject scalable radio frequency communication system includes one or more primary radio frequency integrated circuits (RFICs) and at least one secondary RFIC. Each of the one or more primary RFICs is configured to receive an intermediate frequency (IF) signal from a baseband processor, upconvert the IF signal to a radio frequency (RF) signal, and transmit the RF signal to one or more secondary RFICs. The secondary RFICs under each of the one or more primary RFICs are configured to receive the RF signal from the corresponding primary RFIC, phase shift and amplify the RF signal, and transmit the RF signal via a plurality of antenna elements.
