RF Components

Resources that describe the operation and design of individual RF components such as amplifiers, mixers, etc.

Online RF Technology Certification

This online program has been designed for applications, production, manufacturing engineers and technicians as well as other professionals who need to have a solid background in the fundamentals of working with RF and wireless products. This four part program provides a thorough understanding of RF analytical tools, communications signals, RF devices and test instruments. Starting with basic analytical tools such as the decibel scale, S-parameters and the Smith Chart, this program covers test instrumentation, RF components, and modulation.

Q Versus Bandwidth Relationship

This video explores the mathematical relationship between the Quality factor (Q) and the bandwidth of a circuit's response. While most textbooks and references state that Q and bandwidth are inversely related—meaning a higher Q results in a narrower bandwidth—few delve into the actual math behind this principle. In this video, we go beyond the surface explanation and examine the underlying equations that define this relationship.

Practical MMIC Design

Fabricating MMICs can be high cost and high risk. Because you cannot know if MMICs were fabricated to spec until the fabrication process is completed, cost can easily rise. Design is key to ensuring correct fabrication, minimizing costs, and reducing refabrication. This practical volume is filled with hands-on design techniques and rules of thumb you can use everyday to fabricate MMICs to system specification.

Analysis and Design of Autonomous Microwave Circuits

Presents simulation techniques that substantially increase designers' control over the oscillationin autonomous circuits This book facilitates a sound understanding of the free-running oscillation mechanism, the start-up from the noise level, and the establishment of the steady-state oscillation. It deals with the operation principles and main characteristics of free-running and injection-locked oscillators, coupled oscillators, and parametric frequency dividers.

Mixer Lectures

These lecture notes provide comprehensive coverage of mixer types as used in RF and microwave applications. Three approaches to producing the multiplication of two signals are described: using nonlinear behavior of a diode or transistor, switching, and sampling. Major mixer topologies are also introduced. These notes may be more detailed than what many people are looking for, but they are still worth reading over to gain an understanding of the different mixer strategies.

Mixer Basics Primer

This app note gives a good understanding of the operation of switching type mixers. "Switching type" refers to the implementation of the mixing operation by using the diode or transistor as a switch that turns the RF signal on and off or inverts its polarity at the LO frequency. Another type of mixer implementation is to bias the diode so that it operates in the square law region so that the output includes the square of the input.
