The DA-1G is a general purpose isolation amplifier designed to distribute frequencies from 800 to 1,100 MHz. This Amplifier offers 80 dB of channel-to-channel isolation and 85 dB of reverse isolation at 1 GHz. The low residual phase-noise of the amplifier ensures that the distributed signals are not degraded. The outputs have a low VSWR to minimize environmental effects on frequency distribution through long transmission lines. The standard unit has 1 input and 12 outputs. This Amplifier may operate on 100 to 240 VAC, and +12 to +36 VDC when the optional DC operation option is acquired. When the DA-1G is set up to operate with both AC and DC power sources at the same time, the DC power is used as backup power in case of AC power outages.
