A 64QAM 94GHz CMOS transmitter SoC with digitally-assisted power amplifiers and thru-silicon waveguide power combiners

A 94GHz 64QAM 1Gbps reconfigurable system-on-chip (SoC) CMOS transmitter with digitally-assisted power amplifiers (DAPA) and back-etched thru silicon waveguide power combiners is presented. The SoC includes a 7M gate ASIC with reconfigurable digital modulation and transmit pre-coding. The ASIC feeds two 10b 1.4GHz current-steering DACs followed by a direct… CONTINUE READING
