Mitsubishi Electric Corp. Tuesday said it has developed an MMIC (monolithic microwave IC) chipset for automobile radar to improve driving safety.
The MMIC chipset has electronic beam scanning for 76GHz millimeter-wave radars. The MMIC chips are fabricated using GaAs-pHEMT (pseudo-morphic high electron mobility transistor) processing, similar to the technology Mitsubishi uses to make chips for satellite, defense, and commercial applications.
The MMIC's 76GHz power transmitter amplifier has a output power of 30mW, which Mitsubishi claimed it 1.5 times higher than conventional amplifiers now on the market. The receiver MMIC has less than a 3.5dB noise figure, which the company also claimed is the lowest for this frequency range available.
