HIGH PERFORMANCE DISTRIBUTION AMPLIFIER
The HPDA-100RM is a high performance distribution and isolation amplifier that may contain up to three distribution amplifier modules. Each module provides five unity gain outputs and 100 dB of channel-to-channel isolation, and 110 dB of reverse isolation. The phase noise of the modules is exceptionally low, typically –158 dBc/Hz @ 10 Hz and -174 dBc/Hz @ 10 kHz from the carrier. All the outputs are AC-coupled and the grounds are DC-isolated to reduce the effects of ground loops. The input and outputs have a low VSWR to minimize environmental effects on frequency distribution through long transmission lines.
The HPDA-100RM is available in a 1 U high 19” rack-mount enclosure.
