Trends in automotive safety are pushing radar systems to higher levels of accuracy and reliable target identification for blind spot detection and collision prevention assistance. Consequentially, engineers need to better understand how mounting brackets, fascia, paint color, and bumper assemblies affect the far field radiation patterns of 24 GHz and 77 GHz automotive radar systems.
The L1/L2FPDC is a one input, one output RF device which provides additional GPS L1 and L2 filtering. The frequency response covers both L1 and L2 with low insertion loss. In the normal configuration, the RF output (J1) passes DC from the connected GPS receiver through the input port to the antenna, allowing the GPS receiver to power the antenna.
