HIGH PERFORMANCE DISTRIBUTION AMPLIFIER

HPDA-5 Modules

HPDA-5 OPTIONS

HPDA-5 OEM

The HPDA-5 is available as a HPDA-5 OEM module with one SMA input connector and five SMA output

connectors. The power supply requirements are +/- 12.5 VDC, +/- 0.25 A. Board dimensions are 4.8” x 9.5” x

0.65”.

HPDA-5 NM

The HPDA-5 is also available as an HPDA-5 NM. The HPDA-5 NM has 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 power supply requirements

are +/- (12.5 to 15) VDC, +/-0.25 A.

DESCRIPTION

The HPDA-5 distribution amplifier exceeds the performance required to distribute state-of-the-art atomic

frequency standards. The HPDA-5 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-5 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 HPDA-5 is an enhanced version of the NIST high isolation

distribution amplifier.
