I have several 1Mhz Piezo transducers of different sizes. I want to take some measurements of these piezos by varying the frequency slightly. I generate a nice clean 1Mhz square wave digitaly. The problem is the signal is dying at the base of the transistor when I connect the transformer. Maybe the signal is returning?? And R2 is getting very hot. Just looking for some suggestions, ideas, help? Thanks
Presume the generator impedance is considerably higher than 2.2 ohm, large Ccb of BU406 will load the input respectively.
But there's surely some output voltage swing?
R2 will dissipate some power by design, don't know how you arrived at the shown component values. Some parameters like transformer ratio and inductances are also unknown.
