The Future of Digital RFICs
summary
Radio astronomy example: 230 GHz signals get downconverted to 16 GHz, sampled at two bits, generating ~350 TB/day and ~5 PB total that travel by airplane. CMOS RF transceivers move from 65 nm to 28 nm while digital assist grows from tiny to half the die, pushing calibration and IQ correction into silicon. Moving DPD into the transceiver drops interface rates fivefold and can save ~100 W in 64×64 massive MIMO by removing FPGA work. A 2018 ADR V9000 system‑on‑module (two radios + Zynq + 4 GB memories) demonstrates phase synchronization and scales to 8×8 arrays.
