BDA CONNECTIONS
The BDA AC power is accepted through a standard 3-wire male plug (IEC-320) with
phase, neutral and ground leads. The AC power is wired to a high efficiency DC
switching power supply which is CE and UL approved. The power supply runs the
amplifiers and the Power On lamp. The metal enclosure of the BDA is connected to
ground.
A 9-pin D-Sub connector provides failure alarm output contacts (see diagram next
page) as well as an optional 12 VDC (250mA) auxiliary output.
The RF connections are made via two type “N” female connectors. The RF connector
labeled “BASE” must be connected to the antenna pointing towards the base station.
The RF connection labeled “MOBILE” must be connected to the antenna facing the
area to be covered by the BDA.
The RF connections must be made through cables with characteristic impedance of
50 ohms.
The isolation between the base station antenna and the mobile antenna should
be at least 12 dB higher than the BDA gain. Isolation less than this value can
cause gain ripple across the band. Isolation equal to or less than the BDA gain
will give rise to oscillations which will saturate the amplifiers and possibly
cause damage to the BDA.
