Introduction, definition of terms, Qamp;As
In the operation of electronic systems and circuits, the basic function of a filter is to
selectively pass, by frequency, desired signals and to suppress undesired signals. The amount
of insertion loss and phase shift encountered by a signal passing through the filter is a function of the filter design.
Coupler Theoretical Main Line Loss Calculation
The main-line loss of a coupler is defined as the loss between the input and output ports. Theoretical loss is defined as that of a perfect (lossless)coupler, for which the input power is the sum of the (main-line) output power and the power at the coupled port.
Do it yourself couplers reduce cost
Ever expanding applications of RF and Microwaves for Wireless and Cable applications have revived the development efforts of components at these frequencies.
SM Quadrature Couplers have high performance, low cost
A series of high performance 3 dB quadrature couplers has been developed using Blue Cell™ technology.

The new ebook "Engineering Mathematics: YouTube Workbook” takes learning to a new level by combining free written lessons with free online video tutorials. Each section within the workbook is linked to a video lesson on YouTube where the author discusses and solves problems step-by-step.
The combination of written text with interactive video offers a high degree of learning flexibility by enabling the student to take control of the pace of their learning delivery. For example, key mathematical concepts can be reinforced or more deeply considered by rewinding or pausing the video. Due to these learning materials being freely available online, students can access them at a time and geographical location that suits their needs
The book covers the basic aspects of linear single loop feedback control theory. Explanations of the mathematical concepts used in classical control such as root loci, frequency response and stability methods are explained by making use of MATLAB plots but omitting the detailed mathematics found in many textbooks. There is a chapter on PID control and two chapters provide brief coverage of state variable methods. The approach adopted allows more time to be devoted to controller design by different methods, to compare the results and also to examine the effects of plant parameter variations.
Introduction to Electronic Engineering
This work introduces a reader to the basics of electronic engineering. The book is recommended for those who study electronics. Here, students may get their first knowledge of electronic concepts and basic components. Emphasis is on the devices used in day-to-day consumer electronic products. Therefore, semiconductor components diodes, transistors, and thyristors are discussed in the first step. Next, the most common electronic circuits, such as analogue, differential and operation amplifiers, suppliers and references, filters, math converters, pulsers, logical gates, etc. are covered.
Thermodynamics is an essential subject taught to all science and engineering students. If the coverage of this subject is restricted to theoretical analysis, students will resort to memorising the facts in order to pass the examination. Therefore, this book is set out with the aim to present this subject from an angle of demonstration of how these laws are used in practical situation. This book is designed for the virtual reader in mind, it is concise and easy to read, yet it presents all the basic laws of thermodynamics in a simplistic and straightforward manner; plus many worked examples and a good section of unsolved tutorial problems.
Concepts in Electric Circuits
This book covers fundamental aspects of electric circuits that form the core of many engineering disciplines. In particular, basic circuit elements and their characteristics are presented when connected in an electric network. In addition, techniques to analyse and solve electric circuits are explained in a simple manner and examples are shown to demonstrate each strategy. DC as well as AC circuit analysis is provided with a brief account of filters in the end. Difficult electric circuit concepts such as sinusoids and phasors are explicated in an effective way so that basic understanding can be properly achieved.
