Answer
3
We're
given that the forward power PF is 250 KW and
the VSWR is 1.6 (the frequency is immaterial).
The
reflection coefficient r (rho) is defined as the square
root of the ratio of the reflected power (PR)
and the forward power:
Solving
for PR yields:
The
standing wave ratio (SWR) is defined in terms of the reflection
coefficient by:
|
SWR =
|
1 + |r|
______
1 - |r|
|
Solving
for r yields:
|
|r|
=
|
SWR – 1
_______
SWR + 1
|
Now
we can plug in some numbers:
|
|r|
=
|
1.6 – 1
______
1.6 + 1
|
= 0.23077
|
PR
= 0.230772 × 250 kW = 13.313 kW
