• INTRODUCTION This Operator’s Manual covers the use, operation and installation of the BDA-1000 800 & 900 MHz Bi-Directional Amplifiers (BDA’s). BDA’s are intended to extend radio frequency coverage into areas with coverage deficiency such as inside office buildings, shopping malls, hospitals, tunnels etc. They are designed to be located independent of the Donor Transceiver Site and are equipped with their own antenna systems - one to communicate with the Donor Transceiver Site and the other(s) to communicate with radio equipment in the area with coverage deficiency.
BDA Controller over a 33 to 65 dB range, and an Automatic Gain Control (AGC) provides an additional 23 dB range. PA Power Amplifiers : Optional Linear Power Amplifiers providing 15 dB of additional gain, and up to 20 Watts of RF Power. l Page 5 Kaval Telecom Inc. DCM000000001...

+23.2 dBm output at an input levels higher than –46.8 dBm. Below the AGC turn-on threshold, the output level will decrease linearly with the input signal. With a PA installed in the path, the AGC maximum output level is 15 dB higher. l Page 7 Kaval Telecom Inc. DCM000000001...
BDA CONTROLLER OPERATION The BDA Controller is a microprocessor based part of a Kaval BDA that provides all control, fault monitoring, and settings for the BDA. It interfaces to the 28 VDC Power Supply, the optional 24 VDC Battery (both monitoring, transferring, and charging), control signals to the Boosters, and provides monitored DC power for the Boosters and PA’s.

The physical installation is accomplished by mounting the enclosure onto a vertical wall. Ensure that the unit is mounted in the upright position, as indicated by the upright Kaval logo and the door hinge on the left side of the housing. Four mounting lugs on the enclosure provided for this purpose.
Boosters or PA’s, or excessive ambient temperature (> 60 Other problems may include connector & cable failures or related problems, specification failure in a Booster or PA, etc. Problems of this sort are best referred to Kaval Service, or other supporting RF Test Lab. l Page 16 Kaval Telecom Inc.
