BII-8030 series portable underwater acoustic transmitters are designed for Sonar, artificial acoustic target, communication and bioacoustic application, which integrate power amplifier and impedance matching network into portable water-proof cases. The impedance matching network is customized to match specific impedance between power amplifier and the transducer at operating frequency.

If you are looking for embedded components (lower cost) for your projects, please check out Acoustic Components.

Technical notes
The cable has adverse effects on the power amplifier performances in high frequency range. The longer the cable is, the worse the adverse effects is. If you use long cable in high frequency range, you shall order customized BII-8030 series whose output impedance matches cable and load impedance. In addition,
if you want to use BII-8030 to drive different transducers, you shall specify that BII-8030 matches 50 ohms impedance or cable's characteristic impedance (such as 67 ohms), and the transducers should have impedance matching unit as well to match 50 ohms impedance or cable impedance.

Transducer Connector Assembly

If buyer orders a free hanging, flange mount or flush mount transducer, BII assembles the connector on transducer cable. Buyer dose not need to do any assembly.
If byer orders a thru-hole mount, bolt-fastening mount or end-face mount transducer, BII ships the transducer with wire leads and the mating connector to buyer. After installing the transducer on the mounting wall, buyer shall assemble the connector with transducer cable and solder the wire leads to the connector pins. Note: the size of the mating connector is bigger than mounting hole size of the transducer.
