Linear Amplifiers may or may not be conjugately matched. For maximum power 
transfer to occur both in and out, and for the amplifier to be 
unconditionally stable, there must be a simultaneous conjugate match.
This is not always easy as the input match affects the input match and visa 
versa. However, it CAN be done.
