This paper introduces the application of compact modeling for the automatic design of RF/analog wireless communications building blocks. The need for attaining ever more stringent specifications makes imperious the use of optimization-based techniques. Market competiveness makes design time a major concern, rendering analytical based optimization methodologies a preferable solution to be adopted....
Due to its scale and tight specifications, the European XFEL poses real challenges in the field of low-level radio-frequency (LLRF) control. The implementation of this semi-distributed control system on the microTCA for physics (MTCA.4) platform triggered numerous designs of electronic boards and helped refine the usage of MTCA.4 technology for physics and control systems. This paper presents an overview...
Modern accelerator control systems based on MTCA.4 platform require femtosecond synchronization of RTM cards containing analog front-end electronics for high-speed digital signal processing AMC cards. The main challenge in such system was to realize distribution of few tens of high-quality RF signals to and between RTM cards with high reliability. Usage of coaxial cables with RF connectors in relatively...
This paper describes the design of an Advanced Mezzanine Card (AMC) in the MTCA.4 standard suited for direct analog-to-digital conversion of high-frequency signals up to 2.7 GHz with a maximum ADC clock frequency of 800 MHz. Signal conversion is performed using the undersampling technique. This card was designed for the needs of different control and measurement systems of the FLASH and XFEL accelerators...
This paper presents architecture and simulation results of the analog part of a multichannel integrated circuit (IC) for optical radiation sensors (visible and infrared light) that can be used in high-speed applications. The complete prototype, called Optical Radiation Readout Circuit (ORRC) is composed of analog front end and moderate-resolution analog-to-digital converter (ADC) included in every...
This paper shows the comparison between the simulative evaluation and laboratory measurements of Noise Figure in Remote Keyless Entry (RKE) System working in two variants - 315MHz and 433MHz. The key point is that simulation was made in SPICE-like simulator using the PCB extraction data and models that do not use the telegraphists' equations. The difference between the simulative based values and...
