radars are essential for automotive sensing, medical imaging, and safety- monitoring applications. Among different architectures, frequencymodulated continuous-wave (FMCW) radars are particularly suited for miniature integration targeting portable consumer applications with detection ranges up to a few tens of meters. This translates to a relatively low requirement of transmitter (TX) output peak power and hence is well suited for implementation using lowsupply-voltage CMOS processes. To avoid saturating the receiver (RX) under CW operation, FMCW radars must achieve high TX-to-RX isolation in the front-end. Typically, at least 40dB of isolation is necessary for W-band (75 to 85GHz) FMCW radars, which usually employ separate TX and RX antennas. Hence, this
