MMIC RF Bypassing Capacitor Selection Quick Guide

By Knowles Capacitors Posted On 1.10.2019

Source: Knowles Capacitors blog

Supply noise creates challenges in RF systems where it can mix with RF signals, impacting signal-to-noise ratios and potentially causing spurious output. Thus, high-frequency monolithic microwave integrated circuit (MMIC) amplifiers with broadband gain need to be protected from RF noise on the supply lines. (more…)

RC Snubber Design for SMPS Protection

By InCompianceMag Posted On 1.2.2019

Source: InComplianceMag article

by Bogdan Adamczyk and Bill Spence.

Fundamentals of Inductive Switching and RC Snubber Impact
This is the first of the two articles devoted to the topic of an RC snubber design. In Part I we discuss the fundamentals of the inductive switching and the need for circuit protection. The impact of an RC snubber on the circuit performance is demonstrated through a series of simulations. Part II (to appear in the March 2019 issue of In Compliance) will address the systematic process of the snubber circuit design, together with the simulation and verification through the laboratory measurements.
