本文提出了一种用于5G FR2的26/28/37/39GHz可重构全连接MIMO接收机前端，通过集成片上双工器和带选网络实现52-70dB无校准带外阻塞抑制和-5dBm阻塞容限，支持并发双频或多流单频操作。
25-to-29.5 / 37-to-40GHz fully connected MIMO receiver (RX) front-end for 5G FR2 that enables 52-to-70dB calibration-free inter-band blocker rejection and up to -5dBm 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 4.8Gb/s 64-QAM non-contiguous inter-band carrier aggregation operation. Fully-connected (FC) MIMO architectures have recently gained attention due to their benefits of reduced power consumption and chip area overhead [1-5]. To meet the evolving demand for full coverage of multiple non-contiguous 5G millimeter-wave bands, most MIMO
