HIGH PERFORMANCE DISTRIBUTION AMPLIFIER, 1–50 MHz
The HPDA-5i is an improved version of our previous High Performance Distribution and Isolation Amplifier with performance exceeding that required to distribute state-of-the-art atomic frequency standards. This new model offers the same exceptional low phase noise with a larger frequency bandwidth, greater isolation and improved stability. The Amplifier is intended to be used with a CMA-13SDI Module Crate. 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.
