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. RHBDA BLOCK DIAGRAM DESCRIPTION : Refer to Figure 1 for the following discussion. The RHBDA Downlink path receives RF signals from a Source, amplifies the RF signal, and transmits the signal to the subscriber. The RHBDA Uplink path receives RF signals from the subscriber then amplifies the RF Signal, and sends it to the Base. The Uplink and Downlink occupy two distinct frequency bands. The frequency bands are as follows: 806-824 MHz for the Uplink and 851-869 MHz for the Downlink. Two Filters and one diplexer isolate the Uplink and Downlink paths. 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 Rack Uplink and Rack Downlink paths. The use of these controls is covered in the “OPERATION” section, later in this document. Page 3 Figure 2 1. 2. 3. 4. 5. 6. RHBDA BLOCK DIAGRAM 1.

For situations when multiple carrier signals are present, the rating would have to be reduced by minimum of 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.

(10.45 kg.) approx. ENVIRONMENTAL CONDITIONS: The unit is designed for indoor applications: Operating temperature: - 20°C to + 55°C Storage temperature: - 50°C to + 90°C RHBDA CONNECTIONS The RHBDA Rack 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 Rack power supply runs the amplifiers, the Power ON lamp, and Fiber Optic Transceiver. The metal enclosure of the RHBDA is connected to ground. An optional 9-pin D-Sub connector provides failure alarm output contacts (see diagram next page) as well as an optional 12 VDC (250mA) auxiliary output. The RF connections are made via three type “N” female connector on the back panel (See Figure 3). The RF connection on the Rack Unit labeled “MOBILE” must be connected to the antenna facing the area to be covered by the RHBDA. The RF connector labeled “UL OUT” must be connected to the RF Source Signal going to the Base. The RF connection labeled “MOBILE DL” must be connected to the RF Source Signal from the Base. The RF connections must be made through cables with characteristic impedance of 50 ohms. The isolation between the base station antenna and the mobile antenna should be at least 12 dB higher than the RHBDA gain. Isolation less than this value can cause gain ripple across the band. Isolation equal to or less than the RHBDA gain will give rise to oscillations which will saturate the amplifiers and possibly cause damage to the RHBDA.

BDA INSTALLATION PROCEDURE 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. 2. Ensure that the isolation between the donor antenna and the service antenna is at least 12 dB greater than the RHBDA gain. (Use the higher of the Uplink and Downlink gains reported on the RHBDA test data sheet). 3. Connect the cable from the service antennas to the RHBDA connector labeled “MOBILE” and connect the cable going to the Base RF Signal Source to the RHBDA connector labeled “UL OUT”, and the cable coming from the Base RF Signal Source to the RHBDA connector labeled “DL IN”. 4. Verify that all attenuation settings are positioned at 30 dB. 5. Connect the AC power cord to the Rack Unit. Turn the power switch to the “ON” position. Verify that each Green “Power ON” lamp, Laser alarms LED’s are illuminated. Installation of the Rack RHBDA’s is now complete. To adjust the gain controls to suit the specific signal environment, refer to the next section of the manual. Note: For repeat installations of existing equipment, make sure the attenuation is positioned to its maximum setting (30 dB). After verification of the attenuation, follow the above steps starting with step 1. Page 1 RHBDA OPERATION Refer to figure 1 for adjustment access location and label. Variable Step Attenuator The RHBDA’s gain can be reduced on the Rack Unit by up to 30 dB on the Uplink and Downlink, in 2 dB steps using the variable step attenuators. Gain adjustment is made with rotary switches accessible via the Front panel on the RHBDA enclosure. Arrows on the shafts of these switches point to the value of attenuation selected. RHBDA gain can be determined by subtracting the attenuation value from the gain reported on the RHBDA Test Data Sheet for that side of the unit. The attenuators are labeled for Uplink and Downlink. ALC (Automatic Level Control) To minimize intermodulation products, each amplifier in the RHBDA contains an ALC feedback loop. The ALC circuit senses the output power and limits it to the factory preset level of +5 dBm for the Uplink and +36 dBm for the Downlink. Two red indicator lamps are located on the Front panel which illuminate when the output power exceeds the ALC set point. Two red indicator lamps are located on the Front panel which illuminate when the output power exceeds the ALC set point. To establish proper operating gain on the Rack Unit, start with the Downlink. Observe the red indicator lamp on the front panel. Units are shipping with maximum attenuation. Decrease attenuation one step at a time until the lamp is lit. Then, using the Downlink step attenuator, increase the attenuation until the lamp goes off. The Uplink ALC function is to avoid overloading the fiber optic transceiver. Setting the attenuation of the Uplink will depend on minimum and maximum distance from the mobile to sever antennas. The level indicator is accurate to +/- 0.4 dB of the ALC set point. Operation of the RHBDA-PS8-0.1/25W-55-A at maximum gain (Minimum Attenuation) with greater than -10 dBm average power incident on the MOBILE port may cause damage to the RHBDA.

Maximum Permissible Exposure (MPE) Compliance BDA-PS8-0.1/25W-55-A FCC ID Q8KPS825W60R At the maximum operating frequency of 869MHz (Downlink) and 824MHz (Uplink) the MPE limit for the General Population/Uncontrolled Exposure is as follows: Downlink = 0.58mW/cm2 (f/1500mW/cm2) and Uplink = 0.55mW/cm2 (f/1500mW/cm2). The analysis is provided below. Power Density (S) = EIRP/(4πR²), Therefore, R≥√EIRP/S x 4π From the above calculations, with: Downlink Maximum Antenna Gain = 1dBi Uplink Maximum Antenna Gain = 15dBi Downlink Maximum output power = 36dBm Uplink Maximum output power = 5dBm S = 0.58 mW/cm2 S = 0.55 mW/cm2 EIRP = 37dBm or 5.0 W (worst case) EIRP = 20dBm or 0.1 W (worst case) Therefore, R= 26.19cm (Downlink) R= 3.8cm (Uplink) These are the minimum safe distances for the general population for each antenna.
