Publication number: 20160077196Abstract: A receiver system which may be implemented in an integrated circuit device and suitable for use in automotive radar systems such as collision avoidance systems, includes self test circuitry whereby a local oscillator test signal is generated by an on-board frequency multiplier and mixed in a down-conversion mixer with an RF test signal. The RF test signal is generated on the device by up-conversion of an externally generated low-frequency test signal with the local oscillator test signal. Baseband components may also be checked using test signals of suitable frequency divided down from the local oscillator test signal by a programmable frequency divider. This self test arrangement obviates any need for applying externally generated RF test signals to the IC device.Type: ApplicationFiled: May 29, 2013Publication date: March 17, 2016Applicant: Freescale Semiconductor, Inc.Inventors: Bernhard DEHLINK, Akbar GHAZINOUR, Ralf REUTER
