RF Measurement Concepts - CERN
Published by CERN in the Proceedings of the CAS-CERN Accelerator School: Advanced Accelerator Physics, Trondheim, Norway, 19 29 August 2013, edited by W. Herr, CERN-2014-009 (CERN, Geneva, 2014). RF Measurement Concepts F. Caspers1 and P. Kowina2. 1 CERN, Geneva, Switzerland 2 GSI, Darmstadt, Germany Abstract For the characterization of components, systems and signals in the radiofre- quency (RF) and microwave ranges, several dedicated instruments are in use. In this article the fundamentals of the RF signal techniques are discussed. The key element in these front ends is the Schottky diode which can be used either as a RF mixer or as a single sampler.
For a more precise description, see [2]. There are fundamental limitations when using diodes as dete ctors. The output signal of a diode (essentially DC or modulated DC if the RF is amplitude modula ted) does not contain phase information. In addition, the sensitivity of a diode restricts the input l evel range to about 60 dBm at best, which is
