초록
An MMIC chip set consisting of a power amplifier, a driver amplifier, low noise amplifier, and a frequency doubler has been developed for automotive radar systems at 77GHz. The chip set was fabricated using 0.15μm gate-length InGaAs/InAlAs/GaAs mHEMT process based on 4-inch substrate. The power amplifier demonstrated a measured small signal gain of over 20dB from 76~77GHz with 15.5dBm output power. The chip size is 2mm × 2mm. The driver amplifier exhibited a gain of 23dB over a 76~77 GHz band with an output power of 13dBm. The chip size is 2.1mm × 2mm. The low noise amplifier achieved a gain of 20dB in a band between 76~77GHz with an output power of 10dBm. The chip size is 2.2mm × 2mm. The frequency doubler achieved an output power of -6dBm at 76.5GHz with a conversion gain of -16dB for an input power of 10dBm and a 38.25GHz input frequency. The chip size is 1.2mm × 1.2mm. This MMIC chip set is suitable for the 77GHz automotive radar systems and related applications in W-band. © 2005 IEEE.
