Abstract

Radio frequency (RF) systems in space applications are usually designed for a single task and its requirements. Flexibility is mostly limited to software-defined adaption of the signal processing in digital signal processors (DSP) or field-programmable gate arrays (FPGA). RF specifications, such as frequency band selection or RF filter bandwidth are thereby restricted to the specific application requirements. New radio frequency integrated circuit (RFIC) devices also allow the software-based reconfiguration of various RF specifications. A transfer of this RFIC technology to space systems would have a massive impact to future radio systems for space applications. The benefit of this RFIC technology allows a selection of different RF radio applications, independent of their RF parameters, to be executed on a single unit and, thus, reduces the size and weight of the whole system. Since most RF application sin space system require a high level of reliability and the RFIC is not designed for the harsh environment in space, a characterization under these special environmental conditions is mandatory. In this paper, we present the single event effect (SEE) characterization of a selected RFIC device under proton irradiation. The RFIC being tested is immune to proton induced single event latch-up and other destructive events and shows a very low response to single failure interrupts. Thus, the device is defined as a good candidate for future, highly integrated radio system in space applications.

Highlights

  • IntroductionMost of the radio frequency (RF) parameters depend on the executed application and only the digital signal processing is adjustable by software

  • The German Aerospace Center (DLR), Institute of Space System, is currently working on the development of a highly integrated multi-band software-defined radio (SDR) platform for space application [1,2]

  • Since the DUT is only manufactured on a single fabrication site and no changes in the fabrication process have been announced, it was assumed that the single event effect (SEE) response for both samples would be similar

Summary

Introduction

Most of the RF parameters depend on the executed application and only the digital signal processing is adjustable by software. For this reason, the RF front-end is typically designed with discrete components to the specific application requirements. To allow a software-based reconfiguration on RF front-end related parameters, a new radio frequency integrated circuit (RFIC) technology must be used and needs to be investigated, the performance in a radiation environment for the utilization in space applications. We present the single event effect (SEE) characterization of an RFIC device for the multi-band radio platform purpose under proton irradiation.
