BBV 9744 is a general purpose broadband preamplifier with high gain and low internal noise. Because of the high gain and the good noise figure the system noise is nearly independent of the other components including cable and receiver. These features make the BBV 9744 very useful for the measurement of very low limits. In this case it will be connected directly to the antenna.
The amplifier has 2 stages. The first stage uses an ESD – protected MMIC to prevent defects by unintentional electrostatic discharge.
The BBV 9744 has an aluminium enclosure and uses N-Type flange connectors.
Power supply is very simple because of the built-in voltage regulator. A standard wall plug supply with +12 V DC can be used
