Broadband Pre-amplifier - FPA-18, 1 GHz – 18 GHz

Broadband Pre-amplifier - FPA-18, 1 GHz – 18 GHz
Low noise low power wideband amplifier for increasing sensitivity at field
strength measurements and for general attenuation measurements up to
18 GHz. 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 an
SMA- female connector. A coaxial microwave cable of 0.5 m length is supplied to connect the antenna with the amplifier. The cable is equipped with
N-male and SMA-male connectors.

Transmission of the supplied 0.5m coaxial cable
Usually the amplifier should be installed very close to the antenna. The amplifier housing is equipped with rubber pads for placement on horizontal surfaces. Further there are 22 mm holes in the housing to accept the mounting
tube of Frankonia antennas. The antenna mounting tube is usually oriented
horizontally with the N-female output of the amplifier facing to ground. This
avoids undesired bending of the coaxial cable.
