Abstract

The paper presents a transceiver front-end MMIC intended for the operation in the license free ISM band from 24 GHz to 24.25 GHz and in the UWB band around 24 GHz. The radar principle is FMCW or Doppler. The chip comprises one transmitter with voltage controlled oscillator, power amplifier and two receivers with low-noise-amplifier (LNA) with gain control, quadrature mixers and poly-phase filter each. The functionality inside the chip is controlled via digital control interfaces for power and gain control. For frequency stabilization, an external PLL can be implemented in the radar system. For this, a frequency divider is integrated acting as prescaler. The chip is fabricated in SiGe BiCMOS technology with a chip area of 1.4 × 1.1 mm².
