Dear All,
I am desperately trying to model a Power combiner (for two unequal signals, with same phase) in the DSP domain.
There is a SummerRF in the DSP, but it only adds up two voltages,
Vout = V1 + V2.
If I have two equal signals, I can model a RF power combiner using a SummerRf, followed by an attenuation of sqrt(2), but the problem becomes
tricky when I want to add the power of two unequal signals.
It is because the real summed power is
Vnew ^ 2 = V1 ^ 2 + V2 ^ 2
Vnew = sqrt (V1 ^ 2 + V2 ^ 2)
I have tried to used a Timed2SDC (using the Maths above) but I think it only works properly for single tone signals.
Please advise.
