Infineon RRN7745P & RTN7735P eWLB Fan-Out Package – 77GHz Radar Dies

Product code
EUR 2 990
Sample Flyer Ask for info

The new MRR1Plus 77GHz automotive radar from Bosch integrates receiver and transmitter components from Infineon. These components use the latest SiGe:C HBT technology from Infineon and an effective eWLB / Fan-Out package.

The two RF dies are packaged in the last version of the eWLB, the Fan-Out Wafer level Package developed and manufactured by Infineon. This package has no wire bonding to reduce the inductance and a specific design to increase the heat management using solder balls close to the power RF transistors.

The eWLB package is robust enough to be installed in front automotive module only protected by a plastic lid without underfill. Only a specific pad structure in gold is added on the die.

The RF transistors are the newest generation SiGe:C HBT dies from Infineon. The circuits use advanced insulation structure and modern copper metal layers.

The report includes a complete physical analysis of the packaging process, with details on all technical choices regarding process, equipment and materials. The SiGe HBT are equally analyzed.

The report also features a short comparison with the first eWLB process in order to understand the evolution of technology choices.
