Claim:
1. A circuit configuration for a radar application, comprising: a printed board; semiconductor modules mounted on the printed board, 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 at least one of transmitting and receiving radar signals, and wherein integrated circuits of the semiconductor modules each include at least one HF oscillator and a frequency splitter connected to the HF oscillator; and phase-locked loops for controlling the at least one HF oscillator, 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, wherein the reference signals are feedable to the phase-locked loops via the printed board, and wherein the phase detector is external to the semiconductor module, wherein at least one integrated circuit of the semiconductor modules consists of exactly one HF oscillator and exactly one frequency splitter.
