I am trying to figure out the best way to match impedance values between an amplifier (50 Ohm) which powers a number of transducers (initially 50 Ohm but could change). For one transducer I have previously used a step up transformer (SUT) device between the amplifier and transducer. Now I have multiple transducers.
The signal from the amplifier (40 kHz, 2000 W, 50 Ohm) will be split by a power splitter which feeds 4 transducers. Would it be best to place an SUT between the amplifier and power splitter to match all of the transducers at once, or have some sort of variable capacitor for each transducer (after the power splitter)?
I will also have to use some device to measure the impedance values, I like the idea of the smith chart...
But the instruments are quite costly. Are there any other instruments that would do something similar at 40 kHz?
Thanks for any advice.
