Medientyp: E-Artikel Titel: A 24/77‐GHz SiGe BiCMOS transmitter chipset for automotive radar Beteiligte: Giammello, Vittorio; Ragonese, Egidio; Palmisano, Giuseppe Erschienen: Wiley, 2013 Erschienen in: Microwave and Optical Technology Letters Sprache: Englisch DOI: 10.1002/mop.27425 ISSN: 1098-2760; 0895-2477 Schlagwörter: Electrical and Electronic Engineering ; Condensed Matter Physics ; Atomic and Molecular Physics, and Optics ; Electronic, Optical and Magnetic Materials Entstehung: Anmerkungen: Beschreibung: <jats:title>Abstract</jats:title><jats:p>This article presents a 24/77‐GHz transmitter chipset for automotive radar sensors implemented in a 160/175‐GHz f<jats:sub>T</jats:sub>/f<jats:sub>max</jats:sub> SiGe BiCMOS technology. The chipset adopts a dual‐band architecture consisting of a 24‐GHz section for ultra‐wideband short‐range radar operation, which is also exploited to drive the 77‐GHz long‐range radar transmitter front‐end. The proposed design adopts a single 24‐GHz frequency synthesizer to implement both radar operation modes. The transmitter chipset is able to deliver a maximum output power of 3 dBm and 12 dBm at 24 GHz and 77 GHz, respectively. The 24‐GHz transmitter demonstrates to operate with pulse widths of 0.5 ns and 1 ns in compliance with the transmission mask designed by ETSI. The 77‐GHz transmitter exhibits a power gain of 20 dB, an output power of 12 dBm, and an output referred 1‐dB compression point of 9.5 dBm, while drawing 155 mA from a 2.5‐V supply voltage. © 2012 Wiley Periodicals, Inc.
