Questions about POWER AND VOLTAGE CONVERSION GAIN
Feb 09th, 2006, 9:10pm  
Hi all.

What´s the diference between power conversion gain and voltage conversion gain ? I am designing a double balenced mixer, which the RF and LO inputs are matched ( 50 [Ω] ) but the IF output not. The output impedance is 150 - j210 [Ω] and I would like to drive a 50 [Ω] resistance. How I must to proceed for get these results ( power conversion gain and/or voltage conversion gain ). And about the testbench for this task?

Thank you very much.

P.S.: Sorry for my bad english !

Fabrício

Have a joke, you are French or German?

I konw your meaning.  Voltage gain=Power gain+10log(Zo/Zin)
IF your fiinal drive impedance is the same as the input impedance, 50ohm,
then the two items are the same.
