    What is the best way to connect a PVDF ultrasonic piezoelectric transducer to an mini-circuit amplifier? The transducer only has two wires. The model of the amp is ZFL-1000LN and its input connector is SMA.

    If the input impedance should be 50Ω, should the transducer be connected to the amp through a SMA plug?

    Now the transducer is connected to the amp through a BNC to SMA adapter. The signal displayed on DSO has overshoot. The length of wire of the transducer has been cut to minimum.
