FCC ID: OIW CBDASMRPS9 BDA OVERVIEW: The BDA assembly provides an exceptional repeater/booster performances to extend the coverage area of radio communications in buildings and RF shielded environments. Features such as high linearity power amplifiers are contributing for the overall improved system linearity performances. The unit is based on a duplexed path configuration, having sharp out of band attenuation for improved isolation between the receiving and transmitting paths.

FCC ID: OIW CBDASMRPS9 MECHANICAL SPECIFICATIONS: Size : 9.84 x 9.61 x 4.53 inch (250 x 244 x 115 mm) RF Connectors : N-type Female Weight : 10 Lbs. (5kg.) approx.
FCC ID: OIW CBDASMRPS9 BDA CONNECTIONS The BDA AC power is supplied through a standard 3-wire male plug with phase, neutral and safety ground wires. The AC power is only used to supply a high efficiency DC switching power supply. The two amplifiers (Uplink and Downlink) and the Power On lamp use only DC power. The RF connection is made via two type “N” female connectors. The RF connector labeled “Base” must be connected to the antenna pointing to the base station.
FCC ID: OIW CBDASMRPS9 DIAGNOSTICS GUIDE As mentioned before the BDA should provide long term, care free operation with no need of any periodic maintenance. This section will cover possible problems that may show up after installation. a. Gain Reduction Possible causes: Bad RF cables and RF connections to antennas, Damaged antennas. b. Excessive Intermodulation or Spurious Possible causes: Amplifier oscillation caused by insufficient isolation.
