Abstract :
This paper presents an active pulsed reflector for a FMCW radar system based on the switched injection-locked oscillator principle at 30 GHz. The theory of the active backscatter transponder is extended and system investigations with respect to the impact of phase sampling noise were performed. The circuit has been integrated in a 0.25 μm SiGe BiCMOS technology. On-wafer measurements showed a phase coherent signal amplification of 55 dB with an output power level of -3 dBm.
