Abstract
This work proposes a wideband 26-33GHz MIMO receiver (RX) array that leverages time-modulation operation to achieve concurrent steerable Multi-Beam MIMOs (MB-MIMO) using only one set of array beamformer. The time-modulation enables spectral-spatial mapping that maps the multi-beam information to a single-wire interface. A proof-of-concept 26-33GHz time-modulated RX array with MB-MIMOs is implemented in 45nm CMOS RF SOI. The proposed RX demonstrates S11 < -10 dB across 24 similar to 32 GHz and its maximum conversion gain of 28dB with a 3dB-bandwidth of 26 to 33 GHz. The measured NF is 5.78 dB at 28 GHz with RX input-referred IP1dB of -38dBm. Also, this proposed RX is supported with wideband-16/64QAM single carrier modulations. Show more
