Return Loss to VSWR Conversion Table

2022年3月17日 — Return loss is the loss of signal power due to signal reflection or return by a discontinuity in a fiber-optic link or transmission line.

Return loss is a measure in relative terms of the power of the signal reflected by a discontinuity in a transmission line or optical fiber.

Γ = 10(-Return Loss/20). Return Loss (dB) = -20 log |Γ|. VSWR = [1+1 (-Return l s/20)]/[1-10 (-Return loss/20)] turn Loss (dB) = -20 log [(VSWR-1)/(VSWR+1 ...

If the return loss is 10 dB, 10% of the power is returned. While different systems have different acceptable return loss limits, 15 dB or better is a common system limit for a cable and antenna system.

This table converts between VSWR, Return Loss, reflection coefficient, mismatch loss, reflected power and through power.

2020年10月30日 — For instance, if the return loss is 10 dB, then the return is 10% of the power. Different systems utilize different acceptable return loss ...

2023年6月19日 — When the return loss is <10dB, the antenna will be at VSWR >2, indicating the system will reflect >30% power and the performance of the antenna will be <70%.

2019年9月15日 — If you have return loss < 10 dB it means that your antenna VSWR will be > 2, which means that about 30% of your signal will be reflected ...

2021年8月20日 — 10 dB return loss does not mean 90% of the power is transferred to the load, it means 10% of the power came back. Less than 90% may have reached ...

2023年7月3日 — 回波損耗(RL, Return Loss) 是訊號從源頭注入後，返回、或反射回源頭的功率比例，它在銅雙絞線和光纖纜線系統中為關鍵的性能參數；回波損耗是一種干擾 ...
