HF Circuits and Measurement

Lecturer:

Tutor:

Supervisor:

Department of Radioelectronics

Synopsis:

The subject is aimed at HF circuits and measurement technique. It is intended first of all as the extend of the course RAM. In lectures special emphasis is put on methodology for design of HF circuits utilized in measurement applications. Conception of modern measurement equipments and characteristics of active and passive HF components are discussed as well. The exercises are in the laboratory.
