A Single-Channel RF-to-Bits 36Gbps 8PSK RX with Direct Demodulation in RF Domain

A single-channel 115-135GHz direct demodulation RF-to-bits 8PSK RX is presented. The output of this receiver is demodulated bits, obviating the need for power-hungry high-speed-resolutions ADCs. A novel RF-correlation-based idea is introduced to enable 8PSK direct demodulation. A max conversion gain of 32dB and min NF of 10.3dB was measured. A data rate of 36Gbps was wirelessly measured at 0.3m distance and directly demodulated with a BER of $10^{-6}$. The measured receiver sensitivity at this BER is -41.28dBm.
