FCC ID: QQRBSMR1W60 BDA OVERVIEW: The BDA assembly extends the coverage area of radio communications in buildings and RF shielded environments. The unit features low noise figure and wide dynamic range. It is based on a duplexed path configuration with sharp out of band attenuation allowing improved isolation between the receiving and transmitting paths. BDA BLOCK DIAGRAM DESCRIPTION: Refer to figure 1 for the following discussion.

FCC ID: QQRBSMR1W60 RF EXPOSURE WARNING In order to satisfy the FCC RF exposure requirements, the BDA/antenna installation must comply with the following: The outdoor antenna (Yagi type or similar directional antenna) must be installed so as to provide a minimum separation distance of 1 meter (100 cm) between the antenna and persons within the area. (This assumes a typical antenna with gain of [10.1 dBi, VSWR ≤ 1.5:1, Zo= 50 ohms, and a cable attenuation of between 110 dB).
FCC ID: QQRBSMR1W60 BDA INSTALLATION DO NOT APPLY A.C. POWER TO THE BDA UNTIL CABLES ARE CONNECTED TO BOTH PORTS OF THE BDA AND THE ANTENNAS. 1. Mount the BDA on the wall with the RF connectors pointing DOWN. Using appropriate screws and anchors, attach the BDA to the wall at the four mounting holes on the side flanges. 2. Ensure that the isolation between the donor antenna and the service antenna is at least 12 dB greater than the BDA gain.
FCC ID: QQRBSMR1W60 BDA OPERATION Refer to figure 3 for adjustment access location and label. ALC (Automatic Level Control) To minimize intermodulation products, each amplifier in the BDA contains an ALC feedback loop. The ALC circuit senses the output power and limits it to the factory preset level of +24 dBm.

FCC ID: QQRBSMR1W60 DIAGONOSTICS GUIDE The BDA provides long term, care-free operation and requires no periodic maintenance. There are no user-serviceable components inside the BDA. This section covers possible problems that may be related to the installation or operating environment. 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.
