Increasing cable length in precision video applications - this is the purpose of this article. Traditionally, the physical environment for transmitting video signals over long distances has been the shielded coax cable. Its quality and advantages are well known, and many times designers looking for off-the-shelf solutions do not know that long distance video transmission can be achieved with the same quality but for a much lower price. |

AN16 PCB Layout Guidelines for High Voltage Amplifiers
Submitted by Chris on January 24, 2008.
Standard company design rules for printed circuit boards may not meet the requirements for high voltage amplifiers manufactured by Power Amp Design. The article proposes PCB geometries consistent with successful field applications for high voltage amplifiers. As circuit size shrinks it may not be practical for today’s high voltage amplifiers to adhere to the old PCB trace spacing design rules of yesteryear. As far back as 1980, Sandia National Laboratories did a study to determine new trace spacing rules that would be reliable. Sandia found the then current standards wanting.
