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 24GHz. The radar principle is FMCW. The chip comprises a low-noise-amplifier (LNA) with gain control, quadrature mixers, polyphase filter, Voltage Controlled Oscillator, frequency measurement unit and digital ramp generation unit with internal memory. All the functionality inside the chip is managed via SPI controller. The chip is fabricated in SiGe BiCMOS technology with a chip area of 1.7 × 1.2 mm2.
