In this study, we fabricated a 94-GHz transceiver module for a millimeter-wave (MMW) frequency modulation continuous wave (FMCW) radar sensor. The transceiver modules consist of a waveguide voltage-controlled oscillator (VCO) and Rx module using a single balanced mixer. We designed a mixer with a conversion loss of 6.4 dB, without using an amplifier. Also, the waveguide VCO consisted of an InP Gunn...
In this paper, we present a transceiver module, which operates at the center frequency of 94 GHz, for a frequency modulated continues wave (FMCW) radar. A transmitter part consists of a waveguide voltage controlled oscillator (VCO) and a magic tee for 94 GHz, and a receiver part is essentially a Schottky diode mixer chip mounted on an Al2O3 sapphire substrate. The fabricated transceiver module has...
We present design and fabrication of a 94 GHz radar sensor module. The 94 GHz sensor module has four components including 94 GHz single balanced diode mixer part, waveguide VCO (voltage controlled oscillator) part, magic tee part and bias PCB part. The 94 GHz single balanced diode mixer is developed on Duroid RT 5880 substrate with DC 1346 Schottky diode. The mixer has advantage of good conversion...
The 94 GHz waveguide VCO using InP Gunn diode was designed and fabricated. The fabricated VCO has excellent linearity of 1.7 % at 680 MHz bandwidth and power flatness of 0.68 dBm, respectively. The LPF is designed under -40 dB at 47 GHz and the resonator is designed for frequency generation at 47 GHz. From the measured results the fabricated waveguide VCO has excellent performances: the bandwidth...
