I am looking for a broadband ultrasonic transmitter, with a minimum
frequency response of 15kHz- 65kHz (larger the better). Anyone know of
a good source?

Thanks

Operation in air, water, other?
SPL and at what distance?
Any size and/or geometrical constraints?
Application?

I am looking for an air coupled transmitter
SPL >100dB @ 30cm
< 6cm transmitter diameter ideally
< .1kg in weight ideally
> 60 degree full beam angle

additionally I am looking for a broadband air-coupled ultrasonic
receiver with :
full beam angle > 60 degrees
15-65kHz frequency Response (bigger the better)
element diameter < 5mm
