Abstract

A circuit configuration for radar applications having a printed board and semiconductor modules mounted on it, each of the semiconductor modules including an integrated circuit, a rewiring layer for connecting the integrated circuit to the printed board and at least one antenna element integrated into the semiconductor module and connected to the integrated circuit for transmitting and/or receiving radar signals, the integrated circuit including at least one HF oscillator and a frequency splitter connected to the HF oscillator, the circuit configuration including phase-locked loops for controlling the HF oscillators, each of the phase-locked loops having the frequency splitter and a phase detector for comparing a split-frequency signal of the HF oscillator with a reference signal, and the reference signals may be fed to the phase-locked loops via the printed board.
