Question about Pode Plotter reading interpretation?

[samy555]

hello

When the plotter read voltage gain = +3.979 dB @ 100MHz for the L-impedance matching circuit shown

**broken link removed**

How much power from the source is on the R2 (the load resistance)?
thanks

hi sam.

This LTSpice simulation shows your values are very close.

Is this what you are asking for.??

E.

Alternate way of asking LTSpice the question. Green trace is power input to the network vs freq. Red trace is power in R2 vs frequency.

Note that Pin peaks at ~110MHz, while Po peaks at 100MHz.

How to convert voltage gain to power gain?

Hello
I simulate this circuit using multisim 10
**broken link removed**
The Result on the pode plotter was:
20*log (V_load/V_source) = 3.979 dB @ 100MHz
How can calculate (or measure) 10*log (P_load/P_source)?
thanks

No, I asked the question in the wrong way, and placed the wrong image.
I repeated my question

I want to know how to get (in a quick way) the power gain voltage gain resutled by pode plotter

thanks alot
