Automotive Radar Signal Source Using InP Based MMICs 970175

A 60GHz millimeter-wave signal source for automotive radar was developed with MMICs. This signal source consists of two MMICs; a 30GHz VCO and a 30GHz-to-60GHz frequency doubler. For the transistor of these MMICs, we used the InAIAs/InGaAs on InP pseudomorphic HEMT with a 0.5μm gate length. Because of the high electron mobility and the high sheet charge density, the HEMT performed with sufficient output power gain in the millimeter-wave frequency range. The oscillation frequency of the signal source was controlled from 58.403GHz to 59.373GHz linearly. These frequency characteristics will satisfy the specifications of the FMCW radar system.
