HIGH PERFORMANCE DISTRIBUTION AMPLIFIER

HPDA-5NM Module

DESCRIPTION

The HPDA-5NM is an amplifier module with one input and five outputs in a Nuclear Instrumentation Bin Module

enclosure. The front panel contains a POWER LED, a STATUS LED, one SMA input connector, and five SMA

output connectors. The HPDA-5NM distribution amplifier exceeds the performance required to distribute state-

of-the-art atomic frequency standards. The HPDA-5NM offers 126 dB of channel to channel isolation and 135

dB of reverse isolation. The exceptionally low phase-noise -150 dBc/Hz at 1 Hz implies a short term

frequency stability of 1 part in 10

at 1 s. The HPDA-5NM exhibits a low temperature coefficient of phase of 3

ps/ºC throughout the operating range. The input and outputs have a low VSWR to minimize environmental

effects on frequency distribution through long transmission lines. The power supply requirements are +/- (12.5

to 15) VDC, +/-0.25 A.
