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. The BDA Downlink path receives RF signals from the base station and amplifies and transmits them to the subscriber. The BDA Uplink path receives RF signals from the subscriber and amplifies and transmits them to the base station. The Uplink and Downlink occupy two distinct frequency bands. For example, the SMR frequency bands are as follows: 806-821 MHz for the Uplink and 851-866 MHz for the Downlink. Two 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. The use of these controls is covered in the “OPERATION” section, later in this document.

(8.1kg.) approx. ENVIRONMENTAL CONDITIONS: The unit is designed for indoor applications: Operating temperature: - 20°C to + 50°C Storage temperature: - 50°C to + 90°C BDA 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 Power On lamp. The metal enclosure of the BDA is connected to ground. A 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 two type “N” female connectors. The RF connector labeled “BASE” must be connected to the antenna pointing towards the base station. The RF connection labeled “MOBILE” must be connected to the antenna facing the area to be covered by the BDA. 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 BDA gain. Isolation less than this value can cause gain ripple across the band. Isolation equal to or less than the BDA gain will give rise to oscillations which will saturate the amplifiers and possibly cause damage to the BDA. Page 7 Figure 2 IN BUILDING REPEATER BDA Mechanical Outline Page 8 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 1-10 dB). The indoor antenna (omni directional) must be installed so as to provide a minimum separation distance of 0.2 meters (20 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). Page 9 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. (Use the higher of the Uplink and Downlink gains reported on the BDA test data sheet). 3. Connect the cable from the donor antenna to the BDA connector labeled “BASE” and the cable from the service antennas to the BDA connector labeled “MOBILE”. 4. Open the adjustment access panels on the sides of the BDA and verify that both of the ALC switches are in their factory preset “ON” positions. Close the panels. 5. Connect the AC power cord to the BDA and the…

BDA OPERATION Refer to figure 3 for adjustment access location and label. Variable Step Attenuator BDA gain can be reduced by up to 30 dB in 2 dB steps using the variable step attenuator. Gain adjustment is made with rotary switches accessible via the access door on the BDA enclosure. Arrows on the shafts of these switches point to the value of attenuation selected. BDA gain can be determined by subtracting the attenuation value from the gain reported on the BDA 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 BDA contains an ALC feedback loop. The ALC circuit senses the output power and limits it to the factory preset level of +25 dBm on the Uplink and Downlink. ALC function is selected with on/off toggle switches located on each amplifier and accessible via the access door on the BDA enclosure. A red indicator lamp located on each amplifier illuminates when output power meets or exceeds the ALC set point. The indicator is functional regardless of the position of the ALC switch. Units are shipped with both ALC switches in the “ON” position. To ensure distortion-free operation limited to the set point, keep the ALC’s turned ON. To establish proper operating gain on the Uplink and Downlink sides, start with the Uplink. Observe the red indicator lamp on the Uplink amplifier. If the lamp is lit, verify that the ALC switch is in the “ON” position. Then, using the Uplink step attenuator, reduce the gain until the lamp goes off. Repeat the process for the Downlink. The level indicator is accurate to +/- 0.4 dB of the ALC set point. Operation of BDA-XXX-1/1W-80-A at maximum gain with greater than -45 dBm average power incident on either BASE or MOBILE port can cause damage to the BDA. Page 11
