Mini-BDA CONNECTIONS
The Mini-BDA is powered by a +15 VDC/1.67 Amp Wall Plug-In AC adapter with a
2.5 mm output connector (+24 VDC/1.88 Amp Desk Top AC adapter for 1 Watt
models and (+24 VDC/3.0 Amp Desk Top AC adapter for 2 Watt models). The Wall
Plug-In and Desk Top power adapters are highly reliable and compact, designed for
use in telecommunications. The power adapters are CE & UL approved. The metal
enclosure of the Mini-BDA is connected to ground.
A 9-pin D-Sub connector provides failure alarm output contacts.
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 Mini-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 Mini-BDA gain. Isolation less than this value can cause
gain ripple across the band. Isolation equal to or less than the Mini-BDA gain will give
rise to oscillations which will saturate the amplifiers and possibly cause damage to
the Mini-BDA.
