Page 3: Overview
The BDA-CELLAB/PCSF-33/33-80-AB assembly enhances the coverage area of radio communications in buildings and RF shielded environments. The BDA-CELLAB/PCSF-33/33-80-AB has dual RF paths (Forward / Reverse) to improve coverage in two distinct frequency bands. The unit features low noise figure and wide dynamic range. It is based on a dual duplexed path configuration with sharp out of band attenuation allowing improved isolation between the receiving and transmitting paths. -

ENVIRONMENTAL CONDITIONS: The unit is designed for indoor applications: Operating temperature: - 20°C to + 50°C Storage temperature: - 50°C to + 90°C FCC NOTE: The product has been tested and found to comply with the Federal Communications Commission (FCC) RF Exposure Requirements, pursuant to FCC Part 22 and 24. -
Page 8: Connections
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 LED indicators. - Page 9 OPTIONAL ALARM CONDITIONS: OPTIONAL ALARM CONDITIONS: The alarm monitors current of both uplink and downlink amplifiers. An alarm condition will occur if either uplink or downlink amplifiers are over or under its current tolerance. Also Oscillation detect Alarm would be provided on the other pair dry contacts.

Page 11: Installation
INSTALLATION: DO NOT APPLY A.C. POWER TO THE RHBDA UNTIL CABLES ARE CONNECTED TO BOTH PORTS OF THE RHBDA AND THE ANTENNAS. 1. Set the BDA Rack on the floor or mount on a wall (where applicable). Using appropriate screws and anchors, attach the BDA to the wall at the four mounting holes on the side flanges. -
Page 12: Operation
This setup should be done under RF signal transmit for either path the level indicator is accurate to +/- 0.4 dB of the ALC set point. Note: Operation of BDA-CELLAB/PCSF-33/33-80-AB at maximum gain with greater than -40 dBm average power incidents on the MOBILE or BASE ports could cause damage to the BDA. -
