RF Circuit and PCB and Product Design

Practical RF PCB Design - One of the difficult areas in Electronic Product Design is RF sub-system or Communication Products. A Communications Product Developer has to get Specialized Support from experts in that field.

Plextek from UK is one such firm with such expertise and Experience. Their Technical Information Section gives an insight of important aspects in wireless communication design. Read these first, The Basics of RF System Design, Oscillator Design and Practical RF PCB Design.

Plextek Ltd - Technical Information

Printed Circuit Board Design Guide - This is an useful reference for PCB design and RF. Here it is about "PCB Mounted RF Connectors". Here you see a important rule "the first rule of connectors is that the best connector is no connector at all...". In RF the connectors and their placement needs extra care. At a frequency of 1 GHz, a short PCB track can become an Antenna !

RF circuit design - Theory and Applications

The objective of this textbook is to develop the RF circuit design aspects in such a way that the need of transmission line principles is made clear without adopting an electromagnetic field approach.

RF circuit design - Theory and Applications

Therefore, no EM background is necessary beyond a first year undergraduate physics course in fields and waves as provided by most colleges and universities. Students equipped with the knowledge of basic circuit theory and/or an exposure to microelectronics can use this book and cover the entire spectrum from the basic principles of transmission and microstrip lines to the various high-frequency circuit design procedures.

RF Circuit Design - Theory and Applications by R.Ludwig and P.Bretchko

For the advanced students the entry into this field is often pursued through an electromagnetic field approach, while for the technologists the basic circuit aspect embedded in Kirchhoff's laws is the preferred treatment.
