Characteristics of high frequency transducer

Transducer model RMV 710B 707B 704 711
Central frequency (MHz) 25 30 40 55
Focal length (mm) 15 12.7 6 6
Measured 3 dB band width (MHz) 12–25 17–31 20–40 27–47

The central frequency and focal length measurements are defined by manufacturer’s literature. The 3 dB bandwidth was measured from the frequency spectrum.
