    abstract = {In this paper a 60 GHz monolithic bistatic interferometric
    radar transceiver for high precision measuring is
    presented. The integrated transceiver has been designed using
    a 0.13μm SiGe BiCMOS process from IHP (SG13G2) and
    includes a LNA, a passive six-port structure, detectors, multiplier,
    multiplexer, power amplifier and a digital interface. The chip has
    a size of 2330μm x 1360μm and a maximum power consumption
    of 533mW from a 3.3V power supply. The circuit provides two
    frequency inputs of 7.5 and 15GHz and multiplies them up to
    60 GHz at a minimum input power of -20 dBm. The chip delivers
    a maximum output power of 9dBm at 61 GHz. The input path
    is selectable and the output power is adjustable by a digital
    interface between -23 and 9dBm at 60 GHz. Also the reference
    input power of the six-port and the RF input power can be
    adjusted in a range of 13.2 dB. The minimum input referred
    P1dB is -24.1 dBm. With a multiplexer, the receiver reference can
    be separated from the transmitter, which allows the use of both
    independently from each other. The serial interface is realized
    in 0.13μm CMOS logic and consists of a 20 bit shift register,
    decoder and an analog interface.

A BGT60, stabilized by a PLL-circuit, generates the transmit signal for vivaldi antennas. The system includes also a baseband circuit with adjustable differential amplifier, 24bit@52kSa/s ADC converter for signal sampling and DAC converter for gain and attenuation tuning. Furthermore, the stacked system is directly connected to a FPGA board. A full NIOS2 system is set up to control the radar and send the collected data via ethernet to the PC. C++ software is written to configure the system in an easy comfortable way and to visualize the measured data. Measurements show, that the radar works in a range up to five meter. The maximum distance deviation at 1m is 30µm and the standard deviation is 12.6µm.
