The DA-100 is a wide band general-purpose isolation
amplifier designed to distribute frequencies from 0.3
MHz to 200 MHz. The DA-100 is the low cost solution
for reference frequency distribution. The DA-100 offers
70 dB of channel to channel isolation and 90 dB of
reverse isolation. The exceptionally low phase-noise
-156 dBc/Hz at 10 Hz and –163 dBc/Hz for the noise
floor ensures that your reference signals are not
degraded. The input and outputs have low VSWR to
minimize environmental effects on frequency
distribution through long transmission lines. The inputs
are chassis grounded and all outputs are DC isolated.
The standard unit has two inputs and twenty-four
outputs.
