Description
This contribution describes the design of an MTCA.4-based Rear Transition Module suited for direct sampling of signals in a bandwidth of 5-700 MHz.
The RTM is fully compliant with the DESY Analog class A1 recommendation and features RF backplane support. The board consists of 8 feed-through channels(AC or DC coupled), 1 vector modulator channel and a low-noise clock generation and distribution circuit. Additional features include 6 precise temperature sensors and input power measurement. The card was designed to be used in direct sampling based LLRF control system. The module was tested at the ELBE facility at HZDR. It was used in a direct sampling LLRF control system regulating a 260 MHz normal conducting buncher cavity. The system diagram and test results will be presented.
