A METHOD OF GENERATING SELF-TEST SIGNALS, CORRESPONDING CIRCUIT AND APPARATUS

A self-test signal (RF TEST ) for e.g. radar sensor ICs (10) wherein a local oscillator signal (TX/LO) is generated (122) for mixing (28) with a reception signal (22) by: - applying frequency division (124) to the local oscillator signal (TX/LO) to produce a frequency-divided signal (F DIV , f REF )...

Zusammenfassung:	A self-test signal (RF TEST ) for e.g. radar sensor ICs (10) wherein a local oscillator signal (TX/LO) is generated (122) for mixing (28) with a reception signal (22) by: - applying frequency division (124) to the local oscillator signal (TX/LO) to produce a frequency-divided signal (F DIV , f REF ), - providing a signal generator (320a) for generating the self-test signal (RF TEST ) and - generating the self-test signal (RF TEST ) by operating said the signal generator (320a) with operation of the signal generator monitored or controlled (320) by means of the frequency-divided signal (f DIV , f REF ).
