VOLTAGE STANDING WAVE RATIO (VSWR) / REFLECTION COEFFICIENT RETURN LOSS / MISMATCH LOSS When a transmission line is terminated with an impedance, ZL, that is not equal to the characteristic impedance of the transmission line, ZO, not all of the incident power is absorbed by the termination. ...
A、回波损耗(return loss)又称回程损耗或反射波损耗,用Lr表示;引入回波损耗概念之后,反射系数的大小就可用 dB 形式来表示,为正值; B、反射损耗(reflection loss)概念一般仅用于信源匹配(Zg=Z0)时。它是负载不匹配(ZL不等于Z0)引起的负载中的功率减小的量度,与回波损耗概念不同; ...
Loss in % (L%)is the percentage of power that is lost to the load and returns back to the system as a reflection (It is expressed in %). A high % loss means more power is lost at the load. Mismatch Loss (ML)is a measurement describing the amount of power that will not be avai...
VSWR is a very important parameter in RF transmission systems where a high VSWR can reduce the power delivered to an antenna or system significantly. This can lead to reduced range, heating of cables, damaged amplifiers, etc. Click here to see a Table of corresponding VSWR and Return Loss ...

Return loss in dB = 18 VSWR = 1.28 VSWR to Return loss calculator Following calculator can be used to convert VSWR to corresponding return loss (RL). VSWR (input) : Return Loss in dB (output): Return loss calculation EXAMPLE : VSWR = 1.1 Return loss in dB = 26.44 ...
Here is a JavaScript calculator forVSWR / Return Loss / Reflection Coefficient / Mismatch Error / Improvement Complex Impedances: Return LossVoltage Standing Wave RatioReflection Coefficient Note: VSWR values were used to calculate the other two related values (rounded to 3 significant places) ...
Loss in %is the percentage of power that is lost to the load and returns back to the system as a reflection (It is expressed in %). A high % loss means more power is lost at the load. Mismatch lossis a measurement describing the amount of power that will not be available at the ...
This VSWR calculator will calculate return loss, mismatch loss, loss in percentage and the reflection coefficient. As an added bonus, the results are modifiable and can calculate the other values. In order to improve the VSWR, this calculator also has an extra input for adding an attenuator to...
Return Loss (dB) Mismatch Loss (dB) Overview VSWR which stands for Voltage Standing-Wave Ratio is a measure used to determe the severity of standing waves in a transmission line. Standing waves form when there is a mismatch between the line and the load, and is generally undesirable. The ...
