Device
Integrated, Dual-Band MW / THz Interferometric MHMIC Receiver on a Ceramic Substrate
Spectrum
5.8 GHz, 150 GHz
Novelty
This multiport receiver architecture implements two distinct MW and THz detectors to simultaneously demodulate the MW and THz signals instead of the conventional mixer-based approach using four identical detectors.
Application
Interferometric receiver for simultaneous wireless sensing and communications.
Performance
5.8 GHz, 30 MS/s Symbol Rate, Error Vector Magnitude (EVM) < -30 dB: 4-QAM, 60 Mbps, -31.81 EVM; 256-QAM, 240 Mbps, -35.18 EVM. 150 GHz, 500 MS/s Symbol Rate, EVM < -24 dB; 4-QAM, 1.0 Gbps, -24.58 dBEVM; 64-QAM 3.0 Gbps, -27.72 dB EVM.
