How to select a voltage regulator | Electronics360.For instance, for having a regulated voltage by using a 5 V regulator with 2 V dropout voltage, the input voltage must be equal to at least 7 V, otherwise, it will result in unregulated voltage at the output.The output voltage specification of a typical linear voltage regulator ensures that regulated voltage will be within 5% of nominal voltage.

VSWR and Return loss calculations.This VSWR calculator will calculate return loss, mismatch loss, loss in percentage and the reflection coefficient.In order to improve the VSWR, this calculator also has an extra input for adding an attenuator to improve or reduce the system VSWR.VSWR Loss Calculator.VSWR Reduction using a matched attenuator (assuming a perfect 1:1 Attenuator)

Return Loss cheat sheet.Here is a download of this cheat sheet: VSWR vs.A VSWR of less than 1.5:1 is ideal, a VSWR of 2:1 is considered to bemarginally acceptable in low power applications where power loss is more critical, although a VSWRas high as 6:1 may still be usable with the right equipment.Just in case you don''''''''t care for mathematical equations, here''''''''s a little "cheat sheet" t
VSWR Explained.If the bulb lit brightly at one place on the line and would not light at all further along the line,then he knew to look along the line for an open or short circuit.Short-Circuit TerminationA voltage cannot exist across a perfect short-circuit, that is the voltage can only have the value0 volts at the short-circuit.
