초록

A CMOS centric phase array radar architecture is proposed for long range detection with a high angular resolution and short range with a large field of view at once. And one channel transceiver is implemented in a 65nm CMOS technology and patch array antenna also fabricated on LTCC (Low Temperature Co-fired Ceramic) substrate for small form factor, low power radar. Measured 77GHz I/Q receiver showed a 22dB conversion gain with dynamic gain range of 76dB. Two kinds of VCO showed 69.6∼81GHz and 75.2∼79.2GHz tuning range. A gain of 14.3 dB and P1 dB of 10dBm is obtained at transformer coupled two-stage cascade power amplifier. All the measured results showed a good agreement with simulated one up to 110 GHz by modeling of passive/active test devices and EM (Electro Magnetic) simulations, and showed a the promising candidate for automotive radar applications. © 2012 IEEE.
