08.11.22 -- Filter Basics Part 7: Different Approaches To Q Factor

The telecom industry has undergone rapid development in the past several decades. Digital communications methods have advanced, requiring increased bandwidth and frequency coverage. This advancement has complicated an RF measurement system’s capability to accurately characterize system components. 

This post is an excerpt from the Design Summit series of Qorvo webinars that highlight vital improvements in industry sectors where evolutionary advances are powering next-generation technologies.

In today’s multichannel, wideband multioctave tuning RF receivers, it is often necessary to eliminate unwanted blockers to preserve the fidelity of signals of interest. Filters have played an essential role in reducing these unwanted signals, particularly in the receiver RF front end and local oscillator (LO) portions of these systems. 

In a world that runs on wireless devices and connections, wireless testing is increasingly important. Here is a "right-sizing" approach to managing trade-offs in testing methods and complexity to do what is necessary without breaking your budget.

RF devices might seem esoteric, but designing and analyzing critical components for a number of RF devices is not any more difficult than working with other components. With the right analysis package, you can easily simulate an RF bandpass filter and analyze all aspects of your RF filter.

As a humorous introduction, Rohde & Schwarz was motivated to write this white paper because vehicles are turning into “smartphones on wheels”, especially when considering the massive proliferation of wireless communications in automotive applications.

With this process, Rohde & Schwarz creates and simulates detailed traffic situations for the verification of cellular V2X (C-V2X) connectivity.
