Impedance Matching ...

Hi
I want to connect one amplifier's output that has 4-ohm output impedance, to one load that has only 0.5-ohm impedance. I should match these two different impedances. I know two methods :

1 - Using a load with one 3.5 to 4 ohm resistor in series with amplifier output.
2 - Using a impedance matching transformer.

the first method is easier, and I can build a transformer if second method is best, but I want to know whitch of them is better.

Do you know any other method?

Regards
 

Re: Impedance Matching ...

The transformer is better generally due to low loss compared to a resistor. I assume your input device is a transistor.So you can see power consumed by the resistor as base current* resistor(ohms).
