RADAR FRONT END WITH RF OSCILLATOR MONITORING

The invention relates to an apparatus that, according to an exemplary embodiment, has an RF oscillator for generating an RF oscillator signal at a first frequency and a frequency divider having a division ratio that is fixed during operation. The frequency divider is supplied with the RF oscillator signal and is configured to provide an oscillator signal at a second frequency. The apparatus further has a monitor circuit, to which the oscillator signal at the second frequency is supplied and which is configured to measure the second frequency and to provide at least one digital value that is dependent on the second frequency of the oscillator signal. The at least one digital value is provided on a test contact. 本发明涉及种装置，该装置根据实施例包括用于生成具有第频率的HF振荡器信号的HF振荡器和在运行中具有固定分频比的分频器。分频器被传输HF振荡器信号，并且该分频器构造用于提供具有第二频率的振荡器信号。该装置还具有监控电路，该监控电路被传输具有第二频率的振荡器信号，并且构造用于测量第二频率并且提供取决于振荡器信号的第二频率的至少个数字值。该至少个数字值被提供在测试触点处。
