One of the major benefit of the MicroTCA.4 system is to combine high-speed digital data processing AMC boards with high precision analog signal conditioning RTM boards. We present a multi-channel down-converter based on the MicroTCA.4 system operating in the 1GHz to 4GHz range with an excellent short-term amplitude stability of 6.5E-5 and phase stability of 3.5E-3 degree within a 1MHz bandwidth at 1.3GHz. The down-converter consists of the entire receiver, packed as an RTM board, which down converts the high frequency signal into an intermediate frequency, which is non-IQ sampled by a multi-channel 16-bit digitizer realized as an AMC board. We present all relevant signals along the detection chain and discuss the signal integrity within the RTM and AMC boards for a spurious free operation of the best ADCs available today.

The paper presents first results of an experimental study of narrow band optimal analog adaptive feedback communication system (AFCS) designed for analog signals transmission. The prototype system implemented optimal transmission — reception algorithm derived and studied in [1]-[4] and other authors works. The aim of the study was a comparison of theoretically expected performance of the system (limit accuracy, power and bandwidth efficiency of transmission) and performance provided by its hardware implementation.

The 3rd harmonic system installed in the injector at FLASH (Free-Electron Laser at Hamburg) accelerator allows to achieve ultra short electron bunches with higher peak current, which pushed the limits of high brilliance laser light generation into the so-called water window. The 3rd harmonic system operates at 3.9GHz and requires a very precise phase and amplitude control of the accelerating field below 10fs, which is done by the Low-Level RF system. One of the key component is the RF field detector that converts the detected cavity field signal to an intermediate frequency for digital sampling. The paper presents an overview of the system, particularly the low phase noise reference generator, local oscillator and multichannel down-converter. System scheme and performance are demonstrated.
