Question { Ericsson, 15184 }

what is VSWR?

Answer

Standing wave ratio (SWR) is the ratio of the amplitude of a
partial standing wave at an antinode (maximum) to the
amplitude at an adjacent node (minimum), in an electrical
transmission line.The SWR is usually defined as a voltage
ratio called the VSWR, for voltage standing wave ratio.
VSWR=Vmax/Vmin

Question { Ericsson, 15184 }

what is VSWR?

Answer

Standing wave ratio (SWR) is the ratio of the amplitude of a
partial standing wave at an antinode (maximum) to the
amplitude at an adjacent node (minimum), in an electrical
transmission line.

The SWR is usually defined as a voltage ratio called the
VSWR, for voltage standing wave ratio. For example, the VSWR
value 1.2:1 denotes a maximum standing wave amplitude that
is 1.2 times greater than the minimum standing wave value.
It is also possible to define the SWR in terms of current,
resulting in the ISWR, which has the same numerical value.
The power standing wave ratio (PSWR) is defined as the
square of the VSWR.

What is the ruturn loss?

Answer

In telecommunications, return loss is a measure of power
reflected from imperfections in an electrical or optical
communications link. It is the ratio PR / PT, representing
the power of the wave reflected from the imperfection (PR)
to that of the incident, or transmitted, wave, (PT). For
best performance, the reflected signal should be as small as
possible, meaning the ratio PR / PT should be as small as
possible.Unit is DECIBELS
