A 76 to 81GHz packaged transceiver for automotive radar with FMCW modulator and ADC

A first embedded Wafer Level Ball grid array (eWLB) packaged fully integrated mm-wave 76 to 81GHz transceiver (3TXs and 4RXs channels) with a programmable multichirp FMCW modulator in a 0.13pm SiGe BiCMOS technology is presented. The single chip embeds also programmable VGAs, ADCs and decimators preceding the MIPI CSI2 digital interface needed to deliver the data to the micro. The synthesizer with -95dBc/Hz phase noise at 1MHz offset referenced to 77GHz carrier managed by a programmable timing engine, the 62dB gain receiver with 9dB noise figure and -5dBm of P1dB together with 13dBm of output power in packaged conditions guarantee the short and long range radar applications. Built-in self-test (BIST), and internal timing engine satisfies the ASIL-B ISO26262 safety requirements. Local oscillator input and output buffers embed the cascadable solution for advanced systems with more channels. The paper presents measurements with a target detection at 160m.
