Abstract :
We have developed InP based MMICs for V-band frequency modulated continuous wave (FMCW) radar. For the transistor of these MMICs, we used the InAlAs/InGaAs on InP pseudomorphic high electron mobility transistor (HEMT) with a 0.5 /spl mu/m 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. Millimeter-wave circuitry consists of four kinds of MMIC chips; 30 GHz voltage controlled oscillator (VCO), 30/60 GHz frequency doubler, 60 GHz amplifier and 60 GHz single-balanced mixer. We carried out a prototype experiment of radar transceiver utilizing these MMICs and confirmed FMCW radar operation.
