GHz system on chip (SoC) frequency-modulated continuous-wave (FMCW) radar for short range applications is presented in this paper. The SoC is attached to a carrier printed circuit board (PCB) which in turn is mounted on a radio frequency (RF) frontend using an interposer. Through the use of on-chip antennas, a small form factor is achieved for the SoC, only requiring bond wires for voltage supplies, intermediate frequency (IF) outputs and a 20-GHz local oscillator (LO) input. Measurements reveal a peak effective isotropic radiated power (EIRP) of around 7dBm at 233 GHz with a power consumption of 1.3 W using 1.8 V and 3.3 V supply voltages. Detection of corner reflectors was verified at distances of 1.5 m and 2.5 m using this radar demonstrator.
