SWR and Reflected Power equations

Is there any equations to calculate SWR , Reflected Power and Output Impedance , if you know the Input Power and Impedance at the Source and the Output Power at the Load ?

Hi,

The Below link is a RF calculator which gives the relationship between Returnloss,VSWR and Reflection coeff.

Reflection coeff will gives the percentage of reflected power directed towards the source.From this u can able to calculate the amount of power transfer to the load.

What i want to know is there a way to calculate your SWR and Reflection Power if you have the measured value of the Input Power at the source and Output Power at the load.

I think it cant be possible with only input power and outpower at load.

In other words it'll give only insertion loss of the network.

hi i need to know y return loss is minimum in magnitude at resonant frequency..plz tell me
