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.
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 !
