The high frequency probe used in a wobbler scanning head.

SMC socket ,dimension Ø 7 mm x 18,5 mm

Preamplifier with SMB and SMC sockets , dimension ( housing) Ø19 mm x 12 mm .

All preamplifiers are fed by coaxial output cable ( +5 to +12V ) .

Preamplifiers can be used for any kind of transducers.

The preamplifier board

(dimension 6mm x 14mm x 3mm) can be mounted inside of the

transducer housing .


a)	b)

The echo from the plexi reflector obtained using thick film 28 MHz transduce

a)directly on the transducer and b) after 14 dB amplification in the preamplifier

The bandwidth of the preamplifier .

The impulse and its FFT at the output with 4 nS narrow impulse excitation.

3 dB bandwidth from 10 MHz to 180MHz , Output impedance 50 ohm .
