HIGH PERFORMANCE DISTRIBUTION AMPLIFIER
The HPDA-100i is a High Performance Distribution and Isolation Amplifier with performance exceeding that required to distribute state-of-the-art atomic frequency standards. The HPDA-100i is intended to be used with a CMA-13SDI Crate. All unity gain outputs have 100 dB of channel-to-channel isolation and 110 dB of reverse isolation. 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 power supply requirements are +24 VDC, 0.25 A.
