Abstract

The present invention relates to a modular architecture for transmitting and/or receiving radio frequency (RF) signals using a phased antenna array. A first portion of the RF signal is transmitted/received by a master IC (21) and a second portion of the RF signal is transmitted/received by a plurality of satellite ICs (22). RF distribution between the master IC (21) and the satellite ICs (22) occur over a low-RF-loss interposer (51). The master IC (21) performs upconversion/downconversion between RF signal and a baseband or intermediate frequency signal.
