HPDA-15RMi

HIGH PERFORMANCE DISTRIBUTION AMPLIFIER, 1-50 MHz

The HPDA-15RMi is a High Performance Distribution and Isolation Amplifier with performance exceeding that required to distribute state-of-the-art atomic frequency standards. This model offers exceptionally low additive phase noise and has a frequency bandwidth of 1 MHz to 50 MHz. This amplifier may be used in time scale applications where phase stability is of paramount importance.
The inputs and outputs have a low VSWR to minimize environmental effects on frequency distribution through long transmission lines. All the outputs power levels are monitored and compared to a preset threshold of +7dBm. The HPDA-15RMi-C model has also an open collector alarm signal that is available through the DC connector on the back panel. All HPDA-15RMi are designed to be powered by a 100 to 240 VAC mains source. The "C" model may also be powered by a +12 to +36 VDC power source.
All HPDA-15RMi are available in a 1U high, 19” rack-mount enclosure.
