BDA CONNECTIONS
The BDA AC power is accepted through a 3-wire male plug 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.
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.
