Could some electronics guru please help ? Active impedance matching devices are being widely used in RF equipment.Suppose I have a active impedance matching device under test ('DUT'( How qould I know that it is working, i.e., impedance matching is actually working -- measure the input and out power ? All hints/suggestions would be greatly appreciated -- thanks in advance.
Power draw from the device under test. Maximum power transfer into matched load.
You'd measure the input impedance or the input reflection coefficient. It's easy to do with a network analyzer or a return loss bridge and a signal generator. If you don't have either, you'll have to get creative...
If this is hobbyist activity, the ARRL handbook usually has something on this.
