SDI
Description
The HPDA-15RM-A is a high performance distribution and isolation amplifier. It contains
a high performance distribution module that provides five unity gain outputs. Typical
cross-channel isolation is 125 dB and reverse isolation is typically greater than 135 dB.
The phase noise of the module is exceptionally low, typically –150 dBc/Hz @ Fourier
frequency of 1 Hz and –172 dBc/Hz @ Fourier frequency greater than 10 kHz. Both the
input and output are matched to 50 ohms to obtain better than 25 dB return loss. All
outputs are AC coupled and the grounds are DC isolated to reduce the effect of ground
loops.
