Abstract :
A monolithic microwave integrated circuit (MMIC) chip containing a W-band voltage controlled oscillator (VCO). transmit amplifiers, a receiver low noise amplifier and a mixer is discussed. It is used as the front-end of a homodyne FMCW radar for target range and range rate sensing applications. The 6.9-mm*3.6-mm monolithic chip was fabricated using 0.1- mu m pseudomorphic InGaAs-AlGaAs-GaAs HEMT process technology. The transmitter output power is more than 10 dBm for frequencies in the range 90-94 GHz, and maximum tuning bandwidth is 500 MHz for the VO. The receiver channel has 6-dB conversion gain when the output transmitting power is 10 dBm. A compete radar system has been tested based on the single-chip MMIC front-end. The calculated range and range rate are in good agreement with the measurement data.<>
