5.3 SPARTA: A Scalable, Programmable and Active mm-Wave Dual-Surface Reflect/Transmit Array with Integrated Gain and Phase Control Allowing Bidirectional Signal Routing Capability for Robust and Reconfigurable mm-Wave Networks at 60GHz
Abstract
We present SPARTA, the first dual-surface mm-wave active surface enabling RF signal processing (gain and beamforming) on both sides with multiple transmit and reflect configurations, including simultaneous reception and multi-beam re-transmission in either direction across seven modes. The surface integrates 46 flip-chip bonded custom designed CMOS RFICs (23 per side) operating at 60 GHz on a 14-layer laminate and demonstrates NLOS wireless link closure in both reflect and transmit modes.
