The Radar System IC (RASIC™) series from Infineon is made up by a group of highly integrated functions for the 76-77GHz range for automotive radar. The ICs offer a high level of integration and need only a few/no external components.
Main Applications:
* Adaptive Cruise Control
* Collision Mitigation Systems
* Collision Warning Systems
* BackUp Radar
Highly integrated solutions for the Automotive Radar RF frontend
Infineon has developed a 200 GHz Silicon-Germanium (SiGe) process which is ideally suited for automotive Radar safety applications in the frequency range of 76 to 81 GHz. Automotive qualified Silicon process technology allows much higher integration levels at lower cost and better reliability.
Compared to technologies like Gallium-Arsenide (GaAs) used so far to build radar systems for the automotive industry, Infineon’s SiGe process benefits from its origins in the volume bipolar segment. The unique feature is its robustness which makes it suitable for automotive environments over the full temperature range up to full automotive qualification according to AEC-Q100.
* Single Chip Transceiver for 76-77 GHz
Designed for maximum system integration, the RXN7740 single chip transceiver incorporates all core functions of a radar frontend into a single-chip. The RXN7740, in particular contains: VCO, PA and up to 4 mixers, as well as various on-chip test-functions. Using this component the radar sensor manufacturer can realize a 4-channel monostatic system for Long-Range Applications (e.g. Adaptive Cruise Control, ACC).
* Dielectric Resonance Oscillator (DRO)
The RON7701 DRO can be used to run the RXN7740 in a PLL-type of environment. Combined with an external resonator and the divided output signal of the VCO, the DRO running at 19 GHz provides a highly accurate signal to the PLL circuit.
