Airborne-Rugged Low Profile Frequency Rb Standard (LPFRS/AV1)

Airborne-Rugged Low Profile Frequency Rb Standard (LPFRS/AV1)

  • LPFRS/AV1 airborne rubidium oscillator

LPFRS/AV1 Oscillator Overview

The LPFRS/AV1 is a low-cost, high-performance rubidium source designed for rugged airborne applications. It is compatible to the FEI 5650 model and comes in a low-profile package and 2 outputs. It complies to stringent vibration and shock standards, including low phase noise performance.

The LPFRS/AV1 is RoHS compliant through the NIE exemption of the RoHS Directive 2011/65/EU, Article 4.6/Annex III-7(b), allowing exemptions of Pb free soldering for specific applications such as telecom, including servers, storage array systems, network infrastructure equipment for switching, signalling, transmission, and network management for telecommunications.
