M10.6.8: Integration of downconverters and upconverters in RTM (ATCA)

The Low Level RF control system for FLASH accelerator is composed of among of digitizer modules, digital processing module and Vector Modulator (VM) that are required to close the feedback loop. To achieve the required beam stability for the FLASH a cavity field stability for the accelerating sections in amplitude of 0.01% and in phase of 0.01 degree the design of a high performance Vector Modulator is necessary. The designed module can operate with 1.3 GHz and 3.9 GHz input frequencies used at FLASH. This milestone concerns designing of RTM module with two independent Vector Modulator channels designed according to MTCA specification. The second part of this deliverable refers to a compact version of a multichannel downconverter module in an RTM standard.
