GS3010 - HYB DATA SHEET

DESCRIPTION

The hybrid consists of an LS509 amplifier, four capacitors,

and two selectable bias resistors. The values of the capacitors

assure proper operation of the circuit for the most commonly

required frequency responses.

If a different frequency response is required, external

components can be easily connected to the additional solder

pads connected to various amplifier access points.

The jumper connection of the on-chip 125

Ω resistor and

additional two resistors (58

Ω and 98 Ω) on the hybrid allow

adjustment of the transducer bias current of the receiver.
