Abstract

This paper presents the design and experimental results of a highly integrated 24GHz short-range radar transceiver. The Rx and Tx ICs are mounted by a flip-chip technique on a carrier substrate using metal bumps as interconnect. The module includes on-board Tx and Rx antennas and coplanar transmission lines on a ground shield for the distribution of the RF, LO and IF signals. The module achieves a measured DSB-NF below 9dB and a conversion gain of 38dB across a 2.5GHz DSB IF bandwidth while an I/Q matching of better than 47dB is realized. The single-ended transmit power is 0dBm at 24GHz and the power consumption of the complete system is 1100mW. The complete module size is 65×30mm.
