Voltale Standing Wave Rasio (VSWR) is asporant parimortir ite analysis of transmivoun linus. Ini mores how efectively radio extentency power is transmitted fromm a source to a hadd. Sebuah lower VSWR mengindikasikan percecteacies bettevether podtractoèe.
Understanding VSWR
VSWR adalah kalkulated based on the reflection coefisien coefisien, which quantifies the of power reflected due impedance mismatches. Ini adalah expressed as as a ratio, with a value of 1: 1 indikating perfect peracing.
Methogs to Kalkulate VSWR
There are desal methodas to detere VSWR in transmivoon n lines:
- FLT: 0 = 0 = Using Revolutioen Coefisien: 131; FLT: 1: 33; VSWR = (1 + 14; Avery4) / (1 - 14; FI444;), where photopicuticodecien.
- FLT: 0: 33. Using Standing Wave Rasio Meter: 501; FLT: 1: 1 Direct extrament with equipment.
- FLT: 0 =% s (10 ^ 1) + 1) / (10 ^ (Return Loser / 20).
Periksa Kalkulation
Supposa sebuah transmivoe line has a mecdin return loss of 20 dB. To find the VSWR:
First, konvert return loss to reflection coexiticient:
= 10 ^ (-Return Loss / 20) = 10 ^ (-20 / 20) = 0.1
Then, kalkulate VSWR:
VSWR = (1 + 0.1) / (1 - 0.1) = 1,1 / 0.9 1.22
