Description
The radiation characterisation results of the GNSS Front-end SY1009 are presented.
The SY1009 is manufactured in the IHP 250nm SiGe process and characterised for SEE and TID radiation behaviour.
The RF front-end, synthesiser and IF signal processing chain has been monitored during the radiation tests. No radiation latch-up and functional interrupts events have been observed. For the TID tests the noise figure and gain of the RF front-end as well as the phase noise of the synthesiser have been monitored. Up to 200krad no deterioration of these performance parameters has been observed. In the paper the GNSS front-end circuit architecture is presented with attained electrical measurements.
The radiation set-up, measurement procedure and environment conditions are described. The measurement results and analysis are communicated together with the lessons learned. The digital radiation hardened library used for the SY1009 in this IHP process is made available to IHP and the space community.
