Return Loss in dB: It is a measure of reflected power back from a discontinuity (e.g. connector, impedance mismatch or component) in RF system. It is expressed in decibels (dB). Return loss formula is as follows. RL (dB) = - 20 * Log10(|Γ|) Where, Γ represents reflection coeffi...
Return Loss (RL)is a amount of power that is lost to the load and returns back to the system as a reflection typically expressed in dB. A high return loss means more power is lost at the load. Loss in % (L%)is the percentage of power that is lost to the load and returns back ...
Using the simple formula given below it is possible to convert a given value of VSWR to an equivalent return loss. Note that return loss is given as a ratio expressed in decibels.Return Loss =−20log10(VSWR − 1VSWR + 1)dBReturn Loss =-20log10(VSWR - 1VSWR + 1)dB ...
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. VSWR (Voltage Standing Wave Ratio) is the measure of how efficiently RF power is transmitted and is...

, then theVSWRis defined by the following formula: The reflection coefficient is also known as s11 or return loss. See thevswr tablebelow to see a numerical mapping between reflected power, s11 and VSWR. If you don't want to go through complicated equations to understand the relationship betw...
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 ...
just in different ways. The reflection coefficient is a measurement of the feed line’s mismatch at the antenna. The following formula expresses the reflection coefficient:P =(Z1-Zo)/(Z1+Zo), where Z1refers to the antenna impedance, Z0refers to the feed line impedance, and all variables ...
13. The transmission line of claim 9, wherein said length of said equal-length sections progressively changes essentially according to the formula: ##EQU11## where ls(g)=the length of a section in group g, Ls=the starting section length, ...
Working backwards from the coax stub formula is it possible to determine the velocity factor of an unknown piece of coax. Simply create a coax stub filter of any known length with your suspect coax, then use the above method to measure where the main notch lies. Then use ...
