DA-36 Frequency Distribution Amplifier

Distribution Amplifier Overview

Low-Jitter Transfer of Frequency Reference Signals

The Pendulum DA-36 frequency Distribution Amplifier offers an economical solution to the problem of low-jitter transfer of frequency reference signals over longer distance. Whether the need is to distribute between remote buildings, floors or rooms, or whether the need is a big point-to-multipoint system with thousand of receivers, or just one single point-to-point distribution, DA-36 will do the job.


  • Low-noise and long-distance distribution of reference frequencies
  • Drive up to 2 km of optical fiber
  • Eliminate ground current loop problems
  • Low-loss distribution
  • No noise and interference pick-up
  • Easy to install - flexible, lightweight and small-diameter cable
  • EMP-proof
  • Flexible solution
  • Economical solution
  • RF-to-FO conversion and FO- to-RF conversion

Frequency Distribution Amplifier Details

The Distribution Amplifier DA-36 solves the problem of distributing a reference frequency from a central frequency standard to one or several receiving points.

It offers frequency distribution via optical fiber, or coax cable, with minimal jitter and is designed for reference signals of 10 MHz (sine). The distribution is completely analog, without the use of PLLs or other types of frequency recovery circuits that may introduce jitter or wander. The signal is reconstructed with the help of a narrow-band, high-Q filter, which heavily suppresses noise and distortion.
