A 76-Gbit/s 265-GHz CMOS Receiver With WR-3.4 Waveguide Interface

A 76-Gbit/s 265-GHz CMOS receiver (RX) modularized with a WR-3.4 waveguide interface is presented. It mixer-first RX fabricated using 40-nm technology. The primary design focus simplicity and the resulting low noise loss high conversion gain (CG). To allow for both on-wafer packaged measurements, ON-chip transmission lines are designed such that their characteristics relatively insensitive to presence or absence of adhesive covering chip. chip flip-chip-mounted on multilayer printed circuit board (PCB). Built into PCB transition double-resonant stacked patches wideband operation. module achieves highest wireless data rate 76 Gbit/s 16 QAM, which comparable 80 reported previously probing measurement.
