return loss
... When this condition occurs, the return loss is said to be 0 dB. An open circuit results in the reflected voltage being in phase with the incident voltage; reflected current is opposite polarity of the incident current. With a short circuit, the reflected voltage is out of phase with the incident vol ...

Buck converter
A buck converter is a voltage step down and current step up converter.The simplest way to reduce the voltage of a DC supply is to use a linear regulator (such as a 7805), but linear regulators waste energy as they operate by dissipating excess power as heat. Buck converters, on the other hand, can be remarkably efficient (95% or higher for integrated circuits), making them useful for tasks such as converting the main voltage in a computer (12V in a desktop, 12-24V in a laptop) down to the 0.8-1.8V needed by the processor.
