samy555 Member Jun 20, 2013 #1 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

MikeMl Well-Known Member Most Helpful Member Jun 20, 2013 #3 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. Attachments DF67.jpg 131 KB · Views: 185

samy555 Member Jun 21, 2013 #4 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

samy555 Member Jun 21, 2013 #5 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 Last edited by a moderator: Jun 22, 2013
