Disagree. mmWave on generic CMOS is very impressive. Sure, you can take a SiGe or III-V front end, and marry that up to CMOS back ends, but then you don’t meet the price point. Put in an FPGA, then you are way over price. The baseband bandwidth for FMCW RADAR is not that much, so they are able to pull this off with a DSP. It’s the RF integration that impressed me. I’m presently using some ADI SiGe mmWave ICs (impressive themselves), and those are close to $300 for the TX/RX pair, and that’s only the RF to analog baseband. The TI part is $55 for a fully integrated chip. Just need a PCB/antenna and supply regulators.
