Abstract in another language

In this paper, a scalable, fully digital adjustable, bistatic 60 GHz MIMO six-port transceiver is presented. The circuit features four independent transmitters and four six-port receivers on a single chip. The reference clock frequency of 15 GHz is buffered and multiplied up to 60 GHz. The reference clock is also amplified and feed to an output port of the chip to render possible cascading multiple chips for massive MIMO applications. The receivers each include a VGA to set the reference power level, a LNA for amplification of the weak antenna signal and the six-port structure with three broadside linecoupler, a wilkinson-divider and four power detectors. The transmitters each include a switched-line phase shifter and a power amplifier. The chip has a size of 4 mm x 3.1 mm and a power consumption of 960 mW from a 3.3 V power supply. A minimum input power of -22 dBm is needed at the input clock. The transmitters deliver a maximum output power of 9.1 dBm at 60 GHz. The phase is adjustable in a range from 0° to 325.4°. The successful measurement results indicate, that the MIMO six-port transceiver is well suited for radar applications.
