76-81GHz FMCW satellite Radar-on-Chip sensor
The AWR2544 is a single-chip mmWave sensor composed of a FMCW transceiver. The device is capable of operation in the 76 to 81GHz (EHF) band, includes radar data processing elements, and a rich set of peripherals for in-vehicle networking. AWR2544 provides customers with an additional Launch on package (LOP) antenna feature which facilitates the attachment of antennas directly on to the package. The AWR2544 is built with TI’s low-power 45 nm RFCMOS process and enables unprecedented levels of integration in a small form factor and minimal BOM. The AWR2544 is designed for low-power, self-monitored, ultra-accurate radar systems in the automotive space.
Flyback converter design considerations
The many virtues of flyback converters include being the lowest-cost isolated power converter, easily supplying multiple output voltages, a simple primary-side controller and power delivery of up to 300W. Flyback converters are used in many offline applications from televisions to phone chargers as well telecommunications and industrial applications. Their basic operation can appear intimidating and the design choices are many, especially for those who have not designed one before. Let’s look at some of the key design considerations for a 53VDC to 12V at 5A continuous-conduction mode (CCM) flyback.
Enabling satellite architecture with AWR2544 radar sensors
Satellite architecture is the emerging automotive radar architecture that enables centralised data processing. TI’s AWR2544, engineered using the innovative launch-on-package technology, is the first radar-on-chip in the market designed specifically for this architecture.

Advancements in mmWave Technology: Launch on Package for Automotive Radars
The landscape of automotive radar technology has undergone significant transformation, particularly in the realm of millimeter-wave (mmWave) semiconductor package technology and 3D waveguide antenna. From the initial use of microstrip patch antennas to the evolution towards 3D antennas, the quest for improved performance and efficiency has been relentless. TI’s Launch on Package (LoP) technology enables direct signal transmission from the package radiating element to the 3D antenna through the waveguide within the PCB, thereby enabling efficient electromagnetic signal transfer. In the current era, the spotlight is on LoP technologies, accompanied by sophisticated 3D waveguide antennas for providing better range and object detection.
