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. RHBDA BLOCK DIAGRAM DESCRIPTION : Refer to figure 1 for the following discussion. The RHBDA Downlink path receives RF signals from the base station at a Head-end Optic Fiber Unit*, and translates it to an Optical signal. The signal travels over a fiber optic medium, subsequently receives the signal at the Remote Unit, translates it to back to a RF signal then amplifies it, and transmits the signal to the subscriber. The RHBDA Uplink path receives RF signals at the Remote Unit from the subscriber then amplifies it, and translates it to an Optical signal. The signal travels over a fiber optic medium to the Head-end Fiber Optic Unit. The Head-end Fiber Optic Unit receives the signal, translates it to back to a RF signal then transmits the signal to the base station. The Uplink and Downlink occupy two distinct frequency bands. For example, the frequency bands are as follows: 451.7-452.7 & 460.5-464.6 MHz for the Uplink and 456.7-457.7 & 465.5-469.6 MHz for the Downlink. Five Diplexers isolate the paths and route each signal to the proper amplifying channel. A selectable Automatic Level Control (ALC) allows for output power limiting. A variable step attenuator gives 0 – 30 dB of attenuation in 2 dB steps on the Remote Uplink path and two 0 – 30 dB of attenuation in 2 dB steps on the Remote Downlink path. The use of these controls is covered in the “OPERATION” section, later in this document. Optional DC Input Power Option (S1) The RHBDA is equipped with both AC and DC voltage inputs for power operation. This gives the flexibility of powering the RHBDA with either an AC or DC source. If both sources are connected, the RHBDA will automatically select the stronger source for power. Page 3 Figure 1 1. 2. 3. 4. 9. 8. 7. 6. 5. RHBDA BLOCK DIAGRAM RHBDA-454.7/467.5-0.1/8W-55-A 1.

Power Supply : 110VAC/1.6Amps : 220VAC/0.8 Amps : 50 to 60 Hz *The Manufacturer's rated output power of this equipment is for single carrier operation. For situations when multiple carrier signals are present, the rating would have to be reduced by 3.5 dB, especially where the output signal is re-radiated and can cause interference to adjacent band users. This power reduction is to be by means of input power or gain reduction and not by an attenuator at the output of the device.

ENVIRONMENTAL CONDITIONS : The unit is designed for indoor applications: Operating temperature: - 20°C to + 55°C Storage temperature: - 50°C to + 90°C RF EXPOSURE WARNING In order to satisfy the FCC RF exposure requirements, the RHBDA/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 0.6 meters (60 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 1-10 dB). The indoor antenna (omni directional) must be installed so as to provide a minimum separation distance of 0.6 meters (60 cm) between the antenna and persons within the area. (This assumes a typical wide-beam type antenna with gain of 0-2 dBi, VSWR ≤ 2:1, Zo= 50 ohms, and a cable attenuation of between 1-10 dB).
