I have some questions on impedance matching of transducers using 
transformers.  I have the unmatched complex impedance curve for my 
transducer.  I need to match an amplifier (50 Ohms) to that of my 
transducer (afew ohms & complex).  Questions:

1) For Freq>100kHz & <2MHz, should I use line or conventional 
   transformers ?
2) How do I perform the impedance matching given the unmatched complex 
   imdedance curve of my transducer (LOAD) ?
   E.g. # windings, resultant 3 dB bandwidth calculations, 
        inductors/capacitor tuning??? etc.

Any suggestions or references to help me with the above is greatly 
appreciated.  Thanks a 1.000e6 !!
