Abstract

A 24.25-to-29.5 / 37-to-40GHz fully connected MIMO receiver (RX) front-end for 5G FR2 that enables 52-to-70 dB calibration-free inter-band blocker rejection and up to −5 dBm blocker tolerance is introduced. A compact on-chip diplexer and band-selective network are integrated in the RF chain to reject undesired signals before the mixer. The RX can support concurrent dual-band or multi-stream single-band operation, and achieve$4.8 \text{Gb} / \mathrm{s}$64-QAM non-contiguous inter-band carrier aggregation operation.
