US 12,085,667 B2 · Programmable millimeter wave radar integrated circuit

Abstract

A radar receiver stage on an integrated circuit and a method of processing a received radar signal, are provided. In one aspect, the receiver stage includes a low noise amplifier adapted to be connected to a receiver antenna structure, a first programmable gain amplifier, a first programmable bandpass filter, a second programmable gain amplifier, a second programmable bandpass filter, and a programmable low pass filter. One example method includes selecting a radar system configuration including a system type comprising an FMCW system or a Doppler system, programming at least a first programmable gain amplifier stage to a first gain, programming a first programmable bandpass filter stage to a first center frequency; and programming a programmable low pass filter to a first LPF gain.
