DESCRIPTION

The HPDA-15RM distribution amplifier exceeds the performance required to distribute state-of-the-art atomic

frequency standards. The HPDA-15RM 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-15RM 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-15RM is an enhanced version of the NIST high

isolation distribution amplifier.
