Evaluating S-parameters and other CW stimulus responses is essential for characterising rf amplifiers. An rf vector network analyser (VNA) plays a critical role for this purpose, and proper ...

In Part 3 of RF Fundamentals, we will focus on the challenges related to the need to generate and demodulate analog and digitally modulated signals in the RF signal chain. We’ll review CW signal ...

The operation of an electromechanical switch is based on the simple theory of electromagnetic induction. This switch relies on mechanical contacts for its switching mechanism. In electromechanical ...

Impedance matching is easy if you know the basics. Download the eBook to find out how. During impedance matching, a specific electronic load (R L) is made to match a generator output impedance (R g) ...

Often underestimated, RF field probes are critical to the implementation of a proper radiated immunity test system. All too often, system specifiers gloss over this essential element after having ...
