Miniature Membrane Hydrophone

Compact, high-performance ultrasonic membrane hydrophone

The MMH is a compact, high-performance ultrasonic hydrophone from the Membrane Hydrophone Series. Its smaller, optimized design makes it easy to handle while maintaining the wide high-frequency bandwidth membrane hydrophones are known for. It is an active hydrophone with a 50 Ω terminator for proper impedance matching. Ideal for low-bandwidth or continuous-wave (CW) signals in the low to high MHz range, it also features enhanced resistance to electromagnetic interference (EMI).
