Abstract
Wide-band network for matching a signal-conducting line having a characteristic impedance of 50 ohms to a piezoelectric transmitter having a capacitance C.sub.o and a reactance X.sub.o for a center frequency f.sub.o of the frequency band to be transmitted. Various circuit arrangements and dimensioning rules for the circuit elements are specified as a function of the reactance X.sub.o. The transmitter is a part of an acoustic lens arrangement.
