Overview
Low Noise Low Power Wideband Amplifier for increasing sensitivity at fieldstrength-measurements and for general attenuation measurements up to 28 GHz (useable frequency range).
Low Noise Low Power Wideband Amplifier for increasing sensitivity at fieldstrength-measurements and for general attenuation measurements up to 26.5 GHz (nominal frequency range). A power supply with 12 V / 300 mA DC (e.g. optional AC/DC adaptor, laboratory power supply, rechargeable battery) is required for operation.
In- and Output of the Broadband Amplifier are sensitive to Electrostatic Discharge. Therefore some precaution (discharging coaxial cables and persons) is required before touching the amplifier!
The amplifier Input comes with SMAfemale connectors. A coaxial microwave cable of 0.5 m length is supplied to connect the Antenna with the Amplifier. The cable is equipped with SMA-male connectors. The amplifier is equipped with a female 3/8" camera thread to be connected to a mast, e.g. to AM 9144. The antenna itself is mounted with another 3/8" screw at the amplifier base. The polarisation swivel can easily be achieved within seconds by a further screw in 45° steps using fixing bolts for indexing.
It is very important to avoid bending and torsion of the microwave cable, otherwise persistent damage may be a result. Therefore we recommend to mount the antenna in a way that the antenna connector points into the opposite direction as the RF-Input of the amplifier. This allows a smooth routing the microwave cable with a wide bending radius.
Typical mounting examples together with Horn Antenna BBHA 9170 and Mast AM 9144 at horizontal, 45° and vertical polarisation.
