Reference designs

Automotive RFCMOS 77GHz radar module reference design with object data output over dual CAN FD

This reference design is a solution for a 76 to 81 GHz radar sensor module. The power supplies on board convert the automotive battery input to the required rails for the radar AFE, processors and CAN FD transceiver. All of these functions are included in a small form factor PCB suitable for front (...)

Junction temperature vs. PCB copper coverage area
These are estimated power dissipation and thermal results.
Care must be taken to ensure that device junction temperature
does not exeed the maximum ratings as indicated in the datasheet.

This calculator uses the PCB copper area to estimate the device junction temperature. See notes on usage and calculation method.
