Page 3: Rhbda Overview
RHBDA OVERVIEW: The RHBDA assembly enhances the coverage area of radio communications in buildings and RF shielded environments. The RHBDA 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. -

Page 7: Rhbda Connections
RHBDA CONNECTIONS The RHBDA Remote AC power is accepted through a standard 3-wire male plug (IEC-320) with phase, neutral and ground leads (See Figure 3). The AC power is wired to a high efficiency DC switching power supply which is CE and UL approved. The Remote power supply runs the amplifiers, the Power ON lamp, and Fiber Optic Transceiver. -

Page 9: Rhbda Installation
RHBDA INSTALLATION DO NOT APPLY A.C. POWER TO THE RHBDA UNTIL CABLES ARE CONNECTED TO BOTH PORTS OF THE RHBDA AND THE ANTENNAS. 1. Side the RHBDA into the 19” accessible rack. Mount the RHBDA to the rack. Using appropriate screws, attach the RHBDA to the rack at the four mounting holes on the Front panel. -
Page 10: Rhbda Operation
Uplink will depend on minimum and maximum distance from the mobile to server antennas. The level indicator is accurate to +/- 0.4 dB of the ALC set point. Operation of RHBDA-454.7/467.5-0.1/8W-55-A at minimum attenuation with greater than -30 dBm average power incident on the MOBILE port may cause damage to the RHBDA. -

Page 12: Diagnostics Guide
DIAGNOSTICS GUIDE The RHBDA provides long term, care-free operation and requires no periodic maintenance. There are no user-serviceable components inside the RHBDA. 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 antennae.
