• TECHNICAL SPECIFICATIONS
The BDA provides for both directions a nominal 65dB gain Booster and a 15dB gain Power Amplifier (PA). The linear Booster has
a high gain range of 11 to 65 dB supplying up to 1 Watt of RF Power. The basic gain is adjustable via the BDA Controller over a 31
dB range, and an Automatic Gain Control (AGC) provides an additional 23 dB range. The isolation between the uplink and down-
link paths is provided by two high performance bandpass Duplexers.
